[popis] => The paper aims at deformation and stress analysis of the total replacement of the trapeziometacarpal (TMC) joint using finite element method. The TMC replace-ment serves as a surgical treatment of a hand joint disease called rhizarthrosis. Considering that the replacement is influenced significantly by human tissues when loading in a human body, bones and ligaments are included into the model to reach as realistic conditions as possible. Maximum commonly achievable load is applied on the complex model to present a comparison of various loading vari-ants.

[duvernost_udaju_id] => S
[popis] => This paper deals with the prediction of the mechanical behaviour of lattice structures made by selective laser melting (SLM). The work was divided into two stages where the first was aimed on evaluation of the material model for finite element analysis (FEA) from proposed tensile test specimens. The second stage was using previously evaluated material model for more complex structures composed of periodical truss cells. It was found that the major issue was the real geometry of additively produced specimens. For evaluation, stress-strain diagrams were used. All manufactured parts were made of aluminium alloy AlSi10Mg.

[popis] => This paper deals with an energy harvesting review and analysis of an ambient mechanical energy on a trackside during a passing of a train. Trains provide very high level of vibration and deformation which could be converted into useful electricity. Due to maintenance and safety reasons a rail trackside includes sensing systems and number of sensor nodes is increased for modern transportation. Recent development of modern communication and ultra-low power electronics allows to use energy harvesting systems as autonomous source of electrical energy for these trackside objects. Main aim of this paper is model-based design of proposed vibration energy harvesting systems inside sleeper and predict harvested power during the train passing. Measurements of passing train is used as input for simulation models and harvested power is calculated. This simulation of proposed energy harvesting device is very useful for future design.

[duvernost_udaju_id] => S
[popis] => This paper addresses an important issue of the individual layer thickness influence in a multilayer piezo composite on electro-mechanical energy conversion. The use of energy harvesting systems seems to be very promising for applications such as ultra-low power electronics, sensors and wireless communication. The energy converters are often disabled due to a failure of the piezo layer caused by an excessive deformation/stresses occurring upon the operation. It is thus desirable to increase both reliability and efficiency of the electromechanical conversion as compared to standard concepts. The proposed model of the piezoelectric vibration energy harvester is based on a multilayer beam design with active piezo and protective ceramic layers. This paper presents results of a comparative study of an analytical and numerical approach used for the electro-mechanical simulations of the multilayer energy harvesting systems. Development of the functional analytical model is crucial for the further optimization of new (smart material based) energy harvesting systems, since it provides much faster response than the numerical model.

[popis] => Mixed mode loaded fatigue specimens are not used very frequently. The main reason is that there are still very few qualitative results, which would help with better understanding of how the mode II and mode III are affecting the overall crack propagation. On the other hand, there is considerable number of parts loaded in mixed mode. Studying fatigue failure of roller bearing elements made of polymer material was a motivation to design a new experimental specimen for study of fatigue behaviour of the material loaded in mixed mode. The contribution presents developed FEM model of such specimen with focus on determination of fracture mechanics parameters of propagating cracks.

[popis] => The Cracked Round Bar (abbreviated as CRB in the following) test is used as standardized accelerated testing method for simple ranking of polyethylene pipes based on measuring number of cycles to failure of the cyclically loaded CRB specimen. It can also be used for the slow crack growth rate evaluation of the tested material. This paper deals with the issue of asymmetrically growing cracks in CRB specimens and possible influence of the asymmetry on the results of CRB tests, both the number of cycles to failure and the crack growth rates. It is assumed that the asymmetry is caused by presence of residual stress in the CRB specimens. In the first part of the paper, residual stress in two polyethylene pipes (produced using different extrusion speed) is investigated. Then CRB specimens made from these pipes are also examined regarding the residual stress and the results are compared. The found residual stress distributions are used as input for the following finite element method (FEM) simulation of crack growth in the CRB specimens. The FEM model results are then evaluated and fatigue crack growth rates for asymmetrically growing cracks are calculated. They are compared to the results for symmetrically growing cracks and influence on the results and its significance is discussed. In the end, CRB specimen lifetime prediction is carried out and the influence of the asymmetry on the obtained number of cycles to the failure is also addressed.

In the first part of the paper, residual stress in two polyethylene pipes (produced using different extrusion speed) is investigated. Then CRB specimens made from these pipes are also examined regarding the residual stress and the results are compared. The found residual stress distributions are used as input for the following finite element method (FEM) simulation of crack growth in the CRB specimens. The FEM model results are then evaluated and fatigue crack growth rates for asymmetrically growing cracks are calculated. They are compared to the results for symmetrically growing cracks and influence on the results and its significance is discussed. In the end, CRB specimen lifetime prediction is carried out and the influence of the asymmetry on the obtained number of cycles to the failure is also addressed.

[popis] => The operation of railway axles should fulfill at least two main demands: safety and low operation costs. A significant part of operation costs is given by the length of regular inspection intervals which should reveal potential fatigue cracks in railway axle. The detection of cracks is of a probabilistic nature, therefore their detection is not ensured in all cases. For the safe operation of trains, an existence of potential initial crack should be considered on the axle surface and residual fatigue lifetime should be conservatively determined for this case. Reliable procedure of residual fatigue lifetime estimation should take into account real axle geometry, material characteristics and loading of the railway axle. This paper shows methodology for determination of residual fatigue lifetime (RFL) based on the fracture mechanics approach, taking into account real spectrum of the loading cycles, existence of press-fitted wheels and surface residual stresses given by the thermo-mechanical surface treatment of the railway axle. It is demonstrated that the effect of the residual stresses is significant and should not be neglected in the numerical estimation of residual fatigue lifetime of the axle.

[popis] => A hybrid model of suspended animal cell proposed earlier, with a bendo-tensegrity structure mimicking cytoskeleton, is applied to simulate the global response of the cell under compression and to describe mechanical behaviour of its components. The Finite Element model incorporates Microtubules, Actin Filaments, Intermediate Filaments, nucleus, cytoplasm, and Cell Membrane, all of them with realistic geometrical and material parameters. The unique features of this structural model keep fundamental principles governing cell behaviour, such as interaction between the cytoskeletal components redistributing the prestress of actin filaments throughout all the structure. The force-deformation curve from the simulated compression test with microplates is validated by comparison with the experimental response from literature. The model enables us to investigate the mechanical role of individual celular and cytoskeletal components in intracellular force propagation by means of changing their numbers or parameters. As quantitative characterization of nucleus deformation may be hypothetically decisive for mechanotransduction, the model aims at better understanding of how cellular processes are mechanically controlled.

[nazev_en] => Bendo-tensegrity model simulates compression test of animal cell
[popis_en] => A hybrid model of suspended animal cell proposed earlier, with a bendo-tensegrity structure mimicking cytoskeleton, is applied to simulate the global response of the cell under compression and to describe mechanical behaviour of its components. The Finite Element model incorporates Microtubules, Actin Filaments, Intermediate Filaments, nucleus, cytoplasm, and Cell Membrane, all of them with realistic geometrical and material parameters. The unique features of this structural model keep fundamental principles governing cell behaviour, such as interaction between the cytoskeletal components redistributing the prestress of actin filaments throughout all the structure. The force-deformation curve from the simulated compression test with microplates is validated by comparison with the experimental response from literature. The model enables us to investigate the mechanical role of individual celular and cytoskeletal components in intracellular force propagation by means of changing their numbers or parameters. As quantitative characterization of nucleus deformation may be hypothetically decisive for mechanotransduction, the model aims at better understanding of how cellular processes are mechanically controlled.

[popis] => This paper deals with an innovative approach for SHM with piezoelectric elements utilized as active sensors. The increasing interest in reduction of maintenance costs of aircrafts can be solved by embedding permanent and self-sufficient monitoring networks into the structure of the aircraft in order to prevent structural failures. Piezoelectric elements are currently undergoing a rapid development and due to their inexpensive and non-intrusive nature, they can be used to assemble such monitoring networks. The proposed method utilizes a virtual model of the structure to pinpoint suitable locations for the sensors with respect to the requirement of local and global SHM, serving as an initial point for further research to describe behaviour of the structure during operation and predict any inadmissible state.

[popis] => Energy harvesting is an important topic today. Complex monitoring systems with many nodes need energy sources and vibration energy harvesters (VEHs) could be one type of them. Mathematical model of the VEH is necessary instrument to estimate possible harvested power. This paper deals with piezoelectric VEH in setting as cantilever beam with tip mass. Traditional linear model of this type of VEH is simple, however, it represents the VEH only in one operating point and in another one (another amplitude of excitation vibrations) it could return wrong results. The nonlinear model of VEH is introduced in this paper with its parameters estimation. The nonlinear model is compared with linear model and experiment to demonstrate difference between them in amplitude frequency characteristics. Finally, the average harvested power from harmonic vibrations is measured experimentally and compared with prediction from linear and nonlinear model.

[nazev_en] => Verified nonlinear model of piezoelectric energy harvester
[popis_en] => Energy harvesting is an important topic today. Complex monitoring systems with many nodes need energy sources and vibration energy harvesters (VEHs) could be one type of them. Mathematical model of the VEH is necessary instrument to estimate possible harvested power. This paper deals with piezoelectric VEH in setting as cantilever beam with tip mass. Traditional linear model of this type of VEH is simple, however, it represents the VEH only in one operating point and in another one (another amplitude of excitation vibrations) it could return wrong results. The nonlinear model of VEH is introduced in this paper with its parameters estimation. The nonlinear model is compared with linear model and experiment to demonstrate difference between them in amplitude frequency characteristics. Finally, the average harvested power from harmonic vibrations is measured experimentally and compared with prediction from linear and nonlinear model.
