[nazev] => Prediction of position-dependent stability lobes based on reduced virtual model

[popis] => The stability of a machining process is directly affected by the dynamic response between the tool and the workpiece. However, as the tool moves along the path, the dynamic stiffness of the machine tool changes. To determine the position-dependent dynamic stiffness accurately, a computationally efficient methodology based on a complex virtual model is presented. The virtual model is assembled using Finite Element Method and is effectively reduced via Component Mode Synthesis and transformation to a State-Space Multi-Input-Multi-Output system. Combination of these techniques allows time-efficient response simulations with significantly less computational effort than the conventional full Finite Element models. Furthermore, they describe the behaviour of the complex structure more accurately opposed to the commonly used models based on a simple 1 Degree-of-Freedom systems. The reduced model is used to simulate dynamic response of the structure to a cutting force during operation. A response is measured on an existing machine to modify the virtual model by incorporating fuzzy parameters, such as damping. The stability regions are calculated for variable positions, resulting in position-dependent lobe diagrams. The presented approach can be used to create a map of stable zones to predict and prevent unstable behaviour during operation.

[nazev_orig] => Experimental evaluation of Tusi couple based energy harvester for scavenging power from human motion
[duvernost_udaju_id] => S
[popis] => This paper deals with the experimental performance evaluation of the prototype of a novel inertial energy harvester based on Tusi couple mechanism. The harvester was developed as an autonomous power source for environments with very low frequency and magnitude of mechanical vibrations available. The experiments were conducted using human body during different activities as a source of mechanical excitation, with the prospect of using the harvester for powering up future wearable electronic devices. Four different locations on a single measurement specimen were picked for the harvester placement-back of the head, belt, wrist and ankle. Measurements in each location comprised of walking on a straight and level path at natural speed, walking up and down the stairs, jumping, running, and location-specific activities that were expected to provide significant output power. The measured average output power of the device with dimensions 50x50x20 mm on empirically selected 2 kΩ electrical load reached up to 6.5 mW, obtained with the device attached to the ankle while shaking the leg.

[nazev_orig] => Piezoelectric Micro-fiber Composite Structure for Sensing and Energy Harvesting Applications
[duvernost_udaju_id] => S
[popis] => This paper deals with problematics of energy harvesting and sensing using micro-fiber piezocomposite elements. During the past decade, piezocomposite materials have become an interest of many research activities and due to their favourable properties they have been utilized in wide spectrum of low power applications. Energy harvesting and non-destructive sensing is one of the areas that offers an interesting and challenging opportunity for the application of piezocomposite elements. However, because of the relatively complicated nature of a piezocomposite structure, it is necessary to integrate electronics for signal processing, control, and power management into the sensing or energy harvesting device. There are commercially available solutions in the form of integrated circuits that can be used for general applications of piezoelectric sensors and energy harvesters, they are, however, not optimized for specific piezoelectric materials and applications and do not allow using the elements up to their maximum potential. Therefore, it is necessary to design electronics with respect to the parameters of the element and a create a solution for a specific application. The aim of this paper is to formulate and measure key parameters and characteristics of a specific piezocomposite element and suggest a suitable way of signal processing and power management for sensing and energy harvesting applications.

[nazev_en] => Piezoelectric Micro-fiber Composite Structure for Sensing and Energy Harvesting Applications
[popis_en] => This paper deals with problematics of energy harvesting and sensing using micro-fiber piezocomposite elements. During the past decade, piezocomposite materials have become an interest of many research activities and due to their favourable properties they have been utilized in wide spectrum of low power applications. Energy harvesting and non-destructive sensing is one of the areas that offers an interesting and challenging opportunity for the application of piezocomposite elements. However, because of the relatively complicated nature of a piezocomposite structure, it is necessary to integrate electronics for signal processing, control, and power management into the sensing or energy harvesting device. There are commercially available solutions in the form of integrated circuits that can be used for general applications of piezoelectric sensors and energy harvesters, they are, however, not optimized for specific piezoelectric materials and applications and do not allow using the elements up to their maximum potential. Therefore, it is necessary to design electronics with respect to the parameters of the element and a create a solution for a specific application. The aim of this paper is to formulate and measure key parameters and characteristics of a specific piezocomposite element and suggest a suitable way of signal processing and power management for sensing and energy harvesting applications.

[popis] => For computational modelling of arterial tissues anisotropic constitutive models are preferred for which knowledge on orientation of fibres (principal material directions) is needed. In this paper the impact of different approaches to definition of principal material directions in an anisotropic model of arterial wall is evaluated. Finite element models of different regular shapes were created, as well as two idealized geometries of aortic aneurysms as examples of irregular shapes. In those geometries, difference in maximum principal stresses in the arterial wall was used for evaluation of impact of uncertainty in the principal directions. It was shown that for a cylindric shape the error is negligible but it increases for more irregular geometries. For an asymmetric aortic aneurysm the impact of different orientations of principal material directions was more than 20 % which shows that the uncertainty in orientation of principal material directions may cause significant errors deteriorating completely the advantage of anisotropic material description.

[popis] => Computational modelling of stress-strain states in Abdominal Aortic Aneurysms (AAAs) has become an important tool in assessment of their rupture risk in the last decades. Its possibility to be used in the clinical practice is increasing with every influencing factor considered in the model. Very little attention has been devoted to the impact of the surrounding tissue. AAA is surrounded by less or more compliant connections with other organs along its length. Backbone is rather stiffer than the other surrounded tissue and there are several contacts with the AAA. The AAA may be bended over the backbone which induces additional bending stresses in it.

[nazev_orig] => Stress Intensity Factors for Cracks Emanating from a Notch under Shear-Mode Loading
[duvernost_udaju_id] => S
[popis] => The influence of the notch geometry on the stress intensity factor at the front of the emanating cracks is well known for the opening loading mode. The critical length of the crack corresponding to a vanishing of the influence of the notch stress concentration can be approximately expressed by the formula aI,c = 0.5ρ(d/ρ)1/3, where d and ρ are the depth and radius of the notch, respectively. The aim of the paper was to find out if this formula could be, at least nearly, applicable also to the case of shear mode loading. The related numerical calculations for mode II and III loading were performed using the ANSYS code for various combinations of notch depths and crack lengths in a cylindrical specimen with a circumferential U-notch. The results revealed that, for mode II loading, the critical length was much higher than that predicted by the formula for mode I loading. On the other hand, the critical lengths for mode I and mode III were found to be nearly equal.

[nazev_en] => Stress Intensity Factors for Cracks Emanating from a Notch under Shear-Mode Loading
[popis_en] => The influence of the notch geometry on the stress intensity factor at the front of the emanating cracks is well known for the opening loading mode. The critical length of the crack corresponding to a vanishing of the influence of the notch stress concentration can be approximately expressed by the formula aI,c = 0.5ρ(d/ρ)1/3, where d and ρ are the depth and radius of the notch, respectively. The aim of the paper was to find out if this formula could be, at least nearly, applicable also to the case of shear mode loading. The related numerical calculations for mode II and III loading were performed using the ANSYS code for various combinations of notch depths and crack lengths in a cylindrical specimen with a circumferential U-notch. The results revealed that, for mode II loading, the critical length was much higher than that predicted by the formula for mode I loading. On the other hand, the critical lengths for mode I and mode III were found to be nearly equal.

[popis] => This paper deals with a kinetic energy harvesting device which could harvest electricity from slow swinging movements. This device is based on a bistable design of a piezoelectric cantilever with a tip mass. An additional nonlinear magnetic stiffness is created by magnetic systems for an operation between two stable positions. A slow movement in gravity field could change a potential function of this device and the first stable position is becoming unstable position and this resonator is starting to free oscillate in the second stable position or vice versa. Piezoelectric layers could provide electricity during free oscillating operation in both stable positions. This system could be fixed on a robotic arms, industrial platforms or human body which change a system position in gravity field. For example, a human hand is moved during walking with a slow swing movement and this movement could be used for energy harvesting. This energy harvesting device could generate useful electricity for wearable electronics or biomedical implants. This paper provides mechatronic models which could predict output power during walking.

[duvernost_udaju_id] => S
[popis] => This paper is focused on an analysis of a multilayer ceramic-based piezoelectric vibration energy harvester, which could be excited by ambient vibrations or external forces and thus provide a useful source of electricity for modern electronics. The proposed multilayer concept of the energy harvester enables introduction of tensile / compressive residual stresses inside particular layers. These stresses are intended to be used for enhancement of the harvester´s fracture resistance and simultaneously for the improvement of the energy gain upon its operation. A crack arrest, by means of compressive residual stresses (in the outer “non-piezo” layer), will be utilized to this end. Primarily, the extended classical laminate theory (taking into account the piezoelectric characteristics of selected layers) will be used to define various designs of particular layers with various levels of residual stresses inside them. The weight function method is subsequently employed to select a design, which is most resistant to propagation of preexisting cracks. Selected laminate configurations are verified by means of FE simulations. Such analysis is essential for development of new energy harvesting systems formed of new smart materials and structures, which could be integrated in future development processes.

[popis_en] => The aim of the paper is to quantify the material length scale parameter of the simplified form of the strain gradient elasticity theory (SGET) using first principles density-functional theory (DFT). The single material length scale parameter l is extracted from phonon-dispersions generated by DFT calculations and, for comparison, by adjusting the analytical SGET solution for the displacement field near the screw dislocation with the DFT calculations of this field. The obtained results are further used in the SGET modeling of cracked nano-panel formed by the single tungsten crystal where due to size effects and nonlocal material point interactions the classical fracture mechanics breaks down.

[popis] => A geometrically simplified plane elasticity problem of a finite small crack emanating from a thin interfacial zone surrounding the circular inclusion situated in the finite bounded domain is investigated. The inclusion can model a particle in a composite material. The crack is modelled using the distribution dislocation technique, which represents the so called inner solution or boundary layer of the studied problem. Its application is conditioned by the knowledge of the fundamental solution of the dislocation interacting with the inclusion and its interfacial zone. The fundamental solution is based on the application of Muskhelishvili complex potentials in the form of the Laurent series. The coefficients of the series are evaluated from the compatibility conditions along the interfaces of the inclusion, the interfacial zone and the matrix. Another supplement of the fundamental solution is its utilization for the so-called outer solution, which is the solution of the boundary integral method approximating the stress and strain relations along the external boundary of the domain containing the inclusion. The asymptotic analysis is introduced at the point of crack initiation to control the mismatch between the outer and the inner solutions along the external boundary of the studied domain. The asymptotic analysis results in the evaluation of the stress intensity factors as the leading terms of the asymptotic series expressed from the stress distribution near the crack tip, which lies in the matrix. The topological derivative is used to approximate the energy release rate field associated with the perturbing of the matrix by the finite small crack emanating from the interfacial zone. The assessed values of the energy release rate allow one to study the influence of the interfacial zone dimension and elastic properties on crack initiation under the conditions of finite fracture mechanics.

[popis] => Volumetric compressibility and Poisson's ratios of fibrous soft tissues are analyzed in this paper on the basis of
constitutive models and experimental data. The paper extends the previous work of Skacel and Bursa (J Mech
Behav Biomed Mater, 54, pp. 316–327, 2016), dealing with incompressible behaviour of constitutive models, to
the area of compressibility. Both recent approaches to structure-based constitutive modelling of anisotropic
fibrous biomaterials (based on either generalized structure tensor or angular integration) are analyzed, including
their compressibility-related aspects. New experimental data related to compressibility of porcine arterial layer
are presented and compared with the theoretical predictions of analyzed constitutive models. The paper points
out the drawbacks of recent models with distributed fibres orientation since none of the analyzed constitutive
models seems to be capable to predict the experimentally observed Poisson's ratios and volume change satisfactory.

[popis] => Fused Deposition Modelling (FDM) is a fast-growing 3D printing technology. This technology expands rapidly even in households. Most users set print parameters only according to their own experience, regardless of the final mechanical properties. In order to predict the mechanical behaviour of the FDM-printed components, it is important to understand not only the properties of the printing material but also the effect of the printing process parameters on the mechanical properties. Components manufactured by FDM technology have an anisotropic structure, therefore the filling angle, fill shape, air gap, print orientation, and print temperature affect the resulting mechanical properties. This work deals with the change of mechanical properties depending on the setting of the filling angle, the shape of the filling, the orientation of the parts during printing, the influence of the material and pigment manufacturer

[nazev_en] => Influence of process parameters of printing on mechanical properties of plastic parts produced by FDM 3D printing technology
[popis_en] => Fused Deposition Modelling (FDM) is a fast-growing 3D printing technology. This technology expands rapidly even in households. Most users set print parameters only according to their own experience, regardless of the final mechanical properties. In order to predict the mechanical behaviour of the FDM-printed components, it is important to understand not only the properties of the printing material but also the effect of the printing process parameters on the mechanical properties. Components manufactured by FDM technology have an anisotropic structure, therefore the filling angle, fill shape, air gap, print orientation, and print temperature affect the resulting mechanical properties. This work deals with the change of mechanical properties depending on the setting of the filling angle, the shape of the filling, the orientation of the parts during printing, the influence of the material and pigment manufacturer
