[popis] => The peripheral arterial system consists of small arteries and arterioles, further branching into capillaries. This complex system could be faithfully represented by an asymmetrically structured tree. Such an approach has been used solely in computational analyses, for instance, 1D fluid-structure interaction simulations or multiscale modelling (3D/1D). In vitro flow phantom studies incorporate only pure resistance or two-element Windkessel to mimic the periphery. Thus, the flow and pressure waveforms in these in vitro studies do not qualitatively correspond to those measured in vivo and consequently nor do the input impedance of the periphery, which is rarely shown. To consider the frequency-dependent input impedance of the tree close to that observed in vivo, we created an experimental circuit. It comprises a peristaltic pump as a source of a physiological waveform, an asymmetric structured tree model constructed from commonly available silicon tubes, and a measurement technique for obtaining the input impedance. A good agreement between mathematical and experimental data was found despite some inaccuracies and imperfections in the assembled tree. Therefore, the mathematical model can serve as a design tool for individual in vitro structured tree models representing different peripheral sites. Consequently, the in vitro model could be included in phantom studies as a more realistic boundary condition.

[popis] => This paper focuses on the comparison of the calculation of stress fields under the spherical indenter
determined with analytical and FEM calculations and the identification of the most common cracks initiation
reasons. The most used theory for the description of the contact of sphere and half-space was derived by Hertz.
Huber extended this theory to calculate the stress field under the indenter. If every component of stress tensor
is known, the principal stresses can be derived. The analytically calculated stresses were verified with the FEM
and the initiation and growth of the most common cracks (ring, conical) at spherical indentation was explained.

[duvernost_udaju_id] => S
[popis] => The influence of the Berkovich indenter tilt on the results of the FEM modelling of steel nanoindentation is evaluated in this paper. The shape deviations of the indenter have a great impact on the results of the nanoindentation. The main deviations are the indenter bluntness and indenter tilt. The indenter tilt has an impact on the shape of the contact area and the shape of indentation curves. The X5CrNiCuNb 16-4 steel nanoindentation with Berkovich indenter was modelled and the indentation curves were obtained. The Berkovich indenter was blunted and the tilt of the indenter was changed to determine the influence of the indentation curves by the indenter tilt. The plasticity of the steel was modelled with the multilinear model of material, which was fitted to the data from tensile test. The results showed that growing tilt shifts the indentation curves to higher values of indentation forces and makes unloading curves slightly steeper which is in the agreement with larger contact area. The calculated indentation curves were compared with the indentation curves obtained by experiment and the impact of the indenter tilt to the indentation curves was determined by the comparing of the maximal forces and the shapes of the indentation curves.

[nazev_en] => Influencing the Indentation Curves by the Tilt of the Berkovich Indenter at FEM Modelling of the Steel Nanoindentation
[popis_en] => The influence of the Berkovich indenter tilt on the results of the FEM modelling of steel nanoindentation is evaluated in this paper. The shape deviations of the indenter have a great impact on the results of the nanoindentation. The main deviations are the indenter bluntness and indenter tilt. The indenter tilt has an impact on the shape of the contact area and the shape of indentation curves. The X5CrNiCuNb 16-4 steel nanoindentation with Berkovich indenter was modelled and the indentation curves were obtained. The Berkovich indenter was blunted and the tilt of the indenter was changed to determine the influence of the indentation curves by the indenter tilt. The plasticity of the steel was modelled with the multilinear model of material, which was fitted to the data from tensile test. The results showed that growing tilt shifts the indentation curves to higher values of indentation forces and makes unloading curves slightly steeper which is in the agreement with larger contact area. The calculated indentation curves were compared with the indentation curves obtained by experiment and the impact of the indenter tilt to the indentation curves was determined by the comparing of the maximal forces and the shapes of the indentation curves.

[popis] => The ductile fracture has been one of the most important topics in various branches, such as the automotive, maritime or energy industry. Many approaches have been developed under certain assumptions. The present work focuses on bringing together the microstructural- and phenomenological-based ductile fracture modelling under large plastic deformations, room temperature and quasi-static monotonic loading. The complex yield criterion dependent on three stress invariants with a deviatoric associated flow rule was coupled with several advanced multiaxial ductile fracture criteria. The models were calibrated for the 2024-T351 aluminium alloy and implemented within the commercial explicit finite element code of Abaqus. Two additional tests, which were not covered within the calibration procedure, were simulated to demonstrate good predictability of the onset of cracking and its propagation, modelled by the element deletion technique. It was a small punch test and a three-point bending test of a randomly notched bar.

[popis] => The study compares stresses and strains in the aortic wall derived using different constitutive models for various stress-strain conditions. Structure-based constitutive models with two fibre families with (GOH) and without (HGO) dispersion of collagen fibres are compared. The constitutive models were fitted to data from equibiaxial tension tests of two separated layers of the porcine aortic wall. The initial fit was evaluated with unrestricted parameters and subsequently, the mean angles of the fibre families and the angular dispersion were fixed to the values obtained from histology. Surprisingly, none of the tested models was capable to provide a good quality fit with histologically obtained structural parameters. Fitting the HGO model to experimental data resulted in two fibre families under angles close to +/- 45 degrees, while the GOH model resulted in a nearly isotropic fibre distribution. These results indicate that both of these models suffer from the absence of isotropic strain stiffening. After having modified both models with corresponding additional members based on the Yeoh model of matrix, we obtained a perfect fit to the measured data while keeping the structural histology-based parameters. Finally, significant differences in compliance and resulting stresses and strains between different models are shown by means of simulations of uniaxial tension test, equibiaxial tension tests and inflation of the aorta.

[nazev_en] => Importance of experimental evaluation of structural parameters for constitutive modelling of aorta
[popis_en] => The study compares stresses and strains in the aortic wall derived using different constitutive models for various stress-strain conditions. Structure-based constitutive models with two fibre families with (GOH) and without (HGO) dispersion of collagen fibres are compared. The constitutive models were fitted to data from equibiaxial tension tests of two separated layers of the porcine aortic wall. The initial fit was evaluated with unrestricted parameters and subsequently, the mean angles of the fibre families and the angular dispersion were fixed to the values obtained from histology. Surprisingly, none of the tested models was capable to provide a good quality fit with histologically obtained structural parameters. Fitting the HGO model to experimental data resulted in two fibre families under angles close to +/- 45 degrees, while the GOH model resulted in a nearly isotropic fibre distribution. These results indicate that both of these models suffer from the absence of isotropic strain stiffening. After having modified both models with corresponding additional members based on the Yeoh model of matrix, we obtained a perfect fit to the measured data while keeping the structural histology-based parameters. Finally, significant differences in compliance and resulting stresses and strains between different models are shown by means of simulations of uniaxial tension test, equibiaxial tension tests and inflation of the aorta.

[popis] => This paper deals with advanced techniques of transducing kinetic energy of vibration into useful electricity. Piezoelectricity is widely used as one of the conversion principles and nonlinearities are studied. Motivated by possible applications in aircraft or railways, we seek to find the best system configuration for various forcing conditions to maximize the power generation for more advanced wireless sensing stations. The results for vibration amplitude 0.5 g indicate that monostable regime is suitable for tuning for frequencies lower than the natural frequency of the linear resonator. The best type of oscillation for bistable regime is always in-well single-periodic behavior and is suitable for tuning in the entire frequency range from 20 to 65 Hz. The results show the versatility of this simple energy harvester and could serve as theoretical background for a new tunable energy harvester that will be able to adapt to changes in excitation. This design could also be used in smart sensing structures.

[popis] => This contribution presents a novel smart sensing solution for obtaining operational information from railway trackside. The proposed system consists of strain-based active MFC sensors mounted directly on a rail, that are used to collect data from vibrations and via tailored electronics and wireless transmission systems send them to a cloud-based storage system for further processing. The entire system operates in an ultra-low power regime and allows for automatic threshold-based triggering and data acquisition while being powered either externally or by energy harvesting systems. Acquired signals are stored and processed on a remote server in close to real-time manner to provide operational information about the track and the passing train, detects failures or events endangering the safety of operation, as well as evaluate long-term changes for predictive maintenance purposes. The presented system has been successfully deployed on multiple sites across Czech Republic and Taiwan, an in its current state could already present a competitive solution for automatic operational and health monitoring of railways.

[popis] => This paper deals with advanced techniques of transducing kinetic energy of vibration into useful electricity. It is a well-known fact that the behavior of nonlinear piezoelectric vibration energy harvesters is complex and shows rich dynamics and variability. A nonlinear stiffness is created by additional permanent magnets with separation distance which allows for many qualitatively different types of system behaviour including chaotic operation. A single-degree-of-freedom model of such a nonlinear energy harvesting device is developed and numerical simulations are used to quantify the nonlinearity as well as predict the system behaviour for various design configurations. We theoretically predict the bifurcation response for such a multidisciplinary system. The effect of input base acceleration on bifurcation diagrams is presented. A test rig was developed so that experimental bifurcation diagrams could be made and compared with simulations. The results show that the investigated energy harvester has the potential to be effectively used for powering low-powered sensing devices by its adaptable design.

[nazev_en] => Verification of kinetic piezoelectric energy harvesting model with periodic and chaotic responses
[popis_en] => This paper deals with advanced techniques of transducing kinetic energy of vibration into useful electricity. It is a well-known fact that the behavior of nonlinear piezoelectric vibration energy harvesters is complex and shows rich dynamics and variability. A nonlinear stiffness is created by additional permanent magnets with separation distance which allows for many qualitatively different types of system behaviour including chaotic operation. A single-degree-of-freedom model of such a nonlinear energy harvesting device is developed and numerical simulations are used to quantify the nonlinearity as well as predict the system behaviour for various design configurations. We theoretically predict the bifurcation response for such a multidisciplinary system. The effect of input base acceleration on bifurcation diagrams is presented. A test rig was developed so that experimental bifurcation diagrams could be made and compared with simulations. The results show that the investigated energy harvester has the potential to be effectively used for powering low-powered sensing devices by its adaptable design.

[nazev_en] => Passing Train as Source of Energy for Autonomous LoRa Monitoring System
[popis_en] => This paper deals with a concept of an autonomous railway monitoring system with
energy harvesting source of electric energy. There are several ambient sources of
energy on trackside which could be converted into useful electricity for autonomous
sensors and electronics. A waste energy of passing train is occurred in form of a rail
and sleeper mechanical vibrations. The kinetic energy of mechanical vibration could
be transformed into useful electricity in time of passing trains. The presented kinetic
energy harvesting device could provide autonomous source of energy for sensing and
communication modules. The lab test of energy harvesting device and the autonomous
operation of sensing system with communication is presented. The presented system
was successfully tested with LoRa module, which could operate for a distance of a
few kilometres, and it could transfer information about track condition or dynamic
load, e.g. axle counting or vibration monitoring.

[popis] => The paper reviews the research results to date on critical length parameters of notched aluminum specimens with various notch radii. The Theory of Critical Distances (TCD) was applied in form of the Line Method for the determination of the critical length parameter. This parameter can be used for lifetime predictions of notched components. The output is a comparison of critical length parameters of specimens with various notch radii. Numerical calculations as well as experimentally obtained data were employed in the analysis. Fatigue experiments were performed at fatigue loading device working at ultrasonic frequency of 20 kHz. Thus we were able to reach very high number of cycles to failure.
