[nazev] => Asymptotic solution for interface crack between two materials governed by dipolar gradient elasticity: Amplitude factor evaluation
[nazev_orig] => Asymptotic solution for interface crack between two materials governed by dipolar gradient elasticity: Amplitude factor evaluation
[duvernost_udaju_id] => S
[popis] => The procedure of assessing the amplitude factors in the asymptotic solution for the interface crack between the materials obeying the isotropic gradient elasticity is developed. The boundary conditions at tip of the crack are applied to assemble the eigenvalue problem from which the stress exponents with the appropriate eigenvectors of the regular and auxiliary solutions are evaluated. The amplitude factors of the asymptotic solution are computed from the two-state integrals in which the regular, auxiliary and particular finite element solution represent the independent equilibrium states. The concept of the two-state integral method is based on Betti's reciprocal theorem, which is frequently utilized in classical fracture mechanics. The present work extends its application to the general fracture problem in strain gradient elasticity.

[nazev] => Evaluation of image registration for measuring deformation fields in soft tissue mechanics
[nazev_orig] => Evaluation of image registration for measuring deformation fields in soft tissue mechanics
[duvernost_udaju_id] => S
[popis] => High-fidelity biomechanical models usually involve the mechanical characterisation of biological tissues using experimental methods based on optical measurements. In most experiments, strains are evaluated based on displacements of a few markers and represents an average within the region of interest (ROI). Full-field measurements may improve description of non-homogeneous materials such as soft tissues. The approach based on non-rigid image registration is proposed and compared with standard digital image correlation (DIC) on a set of samples, including (i) complex heterogeneous deformations with sub-pixel displacement, (ii) a typical uniaxial tension test of aorta, and (iii) an indentation test on skin. The possibility to extend the ROI to the whole sample and the exploitation of a natural tissue pattern represents the main assets of the proposed method whereas the results show similar accuracy as standard DIC when analysing sub-pixel deformations. Therefore, displacement and strain fields measurement based on image registration is very promising to characterise heterogeneous specimens with irregular shapes and/or small dimensions, which are typical features of soft biological tissues.

[popis] => Plasticity-induced crack closure (PICC) should be proportional to the amount of plastic deformation near the crack tip. This suggests that softer materials have larger PICC than harder materials, which is often a way of explanation of the observed crack growth rates at low R. However, experimental data showed that at high load ratio R = 0.8 (presumption of no crack closure), the crack growth rates were higher in a high-strength steel limited cyclic hardening), denoted as "hard steel", compared to a steel with pronounced cyclic softening (denoted "soft steel"). At low load ratio R = 0.1 in the Paris regime, it was the opposite: the "hard steel" exhibited slower crack propagation. This means that the crack closure effect was much larger in the harder material. Such behaviour cannot be explained based on classical ideas about crack closure.

[nazev] => Universal Procedure for Correction of Plasticity Effect in Hole‑Drilling Uniform Residual Stress Measurement
[nazev_orig] => Universal Procedure for Correction of Plasticity Effect in Hole‑Drilling Uniform Residual Stress Measurement
[duvernost_udaju_id] => S
[popis] => Background The hole-drilling method is a well-known and widely used technique for the determination of residual stresses, but is limited to materials with linear elastic behaviour. This can be a problem when high residual stresses are measured, since a local yielding can occur due to stress concentration around the drilled hole. Objective If the residual stress exceeds about 80% of the material yield stress, the error caused by the plasticity effect becomes significant. In order to correctly evaluate high uniform residual stresses, a universal procedure for a correction of the plasticity effect is introduced. Methods The procedure uses a neural network and is capable of correcting any combination of uniform residual stresses with magnitudes up to the material yield stress. It also covers a wide range of material parameters, hole diameters, and strain gauge rosettes and it is independent of the orientation of the strain gauge rosette. Results The correction procedure was tested by more than a million randomly generated stress states that covered the entire range of input parameters and performs remarkably well, since the error of the corrected residual stresses is negligible even for the states with residual stress magnitudes equal to the material yield stress. Conclusions The proposed correction extends the application range of the hole-drilling method to high uniform residual stresses and therefore can be very useful for practical measurements.

[duvernost_udaju_id] => S
[popis] => Hydrodynamic tilting-pad journal bearings are
used in high-speed applications with vibration
resistance requirements. Tilting-pad bearings
consist of three or more pads which can be tilted.
Due to this feature, these bearings have much higher
stability in operation than other fixed geometry
hydrodynamic bearings. Increasingly, bearings
lubricated with lower viscosity fluids such as water
are becoming more popular, allowing them to be
used in clean applications without polluting the
environment with oil particles. Wear on the
bearing sliding surfaces is also an important factor
in these applications, not only in terms of bearing
life but also in terms of lubricant contamination.
Therefore, this paper is focused specifically on
bearing wear measurement.

[nazev_en] => Wear Measurement of the Water-Lubricated Tilting-Pad Journal Bearing: Comparison of PEEK and CuBe materials
[popis_en] => Hydrodynamic tilting-pad journal bearings are
used in high-speed applications with vibration
resistance requirements. Tilting-pad bearings
consist of three or more pads which can be tilted.
Due to this feature, these bearings have much higher
stability in operation than other fixed geometry
hydrodynamic bearings. Increasingly, bearings
lubricated with lower viscosity fluids such as water
are becoming more popular, allowing them to be
used in clean applications without polluting the
environment with oil particles. Wear on the
bearing sliding surfaces is also an important factor
in these applications, not only in terms of bearing
life but also in terms of lubricant contamination.
Therefore, this paper is focused specifically on
bearing wear measurement.

[nazev] => VALIDATION OF CRACK LENGTH MEASUREMENT METHOD WITH DIGITAL IMAGE CORRELATION FOR FATIGUE TESTS
[nazev_orig] => VALIDATION OF CRACK LENGTH MEASUREMENT METHOD WITH DIGITAL IMAGE CORRELATION FOR FATIGUE TESTS
[duvernost_udaju_id] => S
[popis] => Digital image correlation (DIC) as a nondestructive contactless technique for real-time surface deformations measurement have become a powerful tool in various applications. It still has great potential in areas such as fracture mechanics (FM), where crack length is important to evaluate fatigue properties of the material, often measured by travelling microscope. The test is frequently stopped and the microscope is manually used,
which takes a long time and the result is strongly dependent on the technician. Automated DIC measurement could help to solve these issues.
Therefore, this paper is focused on validation of the method, which would enable such automation and could be more robust and accurate than currently used DIC methods for crack length measurement.

[nazev_orig] => Achievable accuracy of resonating nanomechanical systems for mass sensing of larger analytes in GDa range
[duvernost_udaju_id] => S
[popis] => Measurement of larger analytes such as many chemical and biological structures or viruses in gigadalton (GDa) range is a reminding fundamental task in analytical chemistry and life sciences, which can be possibly resolved with the resonating nanomechanical systems. Common approaches to mass sensing with these systems model the bound analyte as a point particle and assume the analyte does not change the vibrational mode shapes. However, for larger analytes their stiffness and size not only affect the resonant frequencies but also cause the significant changes in the vibrational mode shapes making their measurement highly challenging and still under-explored problem. Here, we develop a 3D model capable to accurately predict the resonant frequencies and vibrational mode shapes of the resonating nanomechanical systems with the bound analyte of arbitrary properties and size. Then, we examine in details the impact of analyte properties, size and its position of attachment on the resonant frequencies and vibrational mode shapes and, correspondingly, resolve a dispute over the achievable detection limits of the nanomechanical systems, especially for mass sensing of larger analytes. Furthermore, we identify three different sensing regimes, that is, the ultra-light, light and heavy, for which the effects of the analyte mass, stiffness, its size and the position of attachment on the accuracy of the determined mass can be separated. For the ultra-light regime (mass ratio < 10-3) the analyte stiffness and its size affect notably the resonant frequencies, the point mass approximation is inaccurate and the analyte can be identified by its mass and stiffness. For the light regime the point mass approximation is accurate, while for the heavy one (mass ratio > 2 center dot 10- 2) the mass effect dominates the frequency response and alters the vibrational mode shapes which, for the common approaches, yields the errors in the determined analyte mass. Finally, we also propose an easily accessible approach for the identification of larger analytes (in GDa range) that does not require the advanced computational tools or experimental setup, applicable to the majority of the clamped-clamped ends resonating nanomechanical systems.

[popis] => With the aim of improving the excellent mechanical properties of the SLM-produced
AlSi10Mg alloy, this research focuses on post-processing using ECAP (Equal Channel Angular Pressing).
In our article, two different post-processing strategies were investigated: (1) low-temperature
annealing (LTA) and subsequent ECAP processing at 150 C; (2) no heat treatment and subsequent
ECAP processing at 350 C, 400 C and 450 C. The microstructure and mechanical properties of this
alloy were analyzed at each stage of post-treatment. Metallographic observations, combined with
SEM and EBSD studies, showed that the alloys produced by SLM have a unique cellular microstructure
consisting of Si networks surrounding the Al-based matrix phase. Low-temperature annealing
(LTA), followed by ECAP treatment, facilitated the microstructural evolution of the alloy with partial
breakup of the Si network and observed nucleation of -Si precipitates throughout the Al matrix.
This resulted in a Vickers microhardness of 153 HV and a yield strength of 415 MPa. The main results
show that post-processing of SLM-produced AlSi10Mg alloys using ECAP significantly affects the
microstructural evolution and mechanical properties of the alloy.

SLM-Fabricated AlSi10Mg Alloy Post-Processed Using Equal
Channel Angular Pressing (ECAP)
[popis_en] => With the aim of improving the excellent mechanical properties of the SLM-produced
AlSi10Mg alloy, this research focuses on post-processing using ECAP (Equal Channel Angular Pressing).
In our article, two different post-processing strategies were investigated: (1) low-temperature
annealing (LTA) and subsequent ECAP processing at 150 C; (2) no heat treatment and subsequent
ECAP processing at 350 C, 400 C and 450 C. The microstructure and mechanical properties of this
alloy were analyzed at each stage of post-treatment. Metallographic observations, combined with
SEM and EBSD studies, showed that the alloys produced by SLM have a unique cellular microstructure
consisting of Si networks surrounding the Al-based matrix phase. Low-temperature annealing
(LTA), followed by ECAP treatment, facilitated the microstructural evolution of the alloy with partial
breakup of the Si network and observed nucleation of -Si precipitates throughout the Al matrix.
This resulted in a Vickers microhardness of 153 HV and a yield strength of 415 MPa. The main results
show that post-processing of SLM-produced AlSi10Mg alloys using ECAP significantly affects the
microstructural evolution and mechanical properties of the alloy.

[popis] => The paper aims at exploitation of neural networks to create a required pulse wave in a compliant hydraulic circuit, representing arterial architecture. The pulse wave is evoked with a roller pump with its rotation speed controlled by a step motor. Peripheral resistance is created by a system of compliant silicon tubes mimicking arterial tree. The measured pressure waves in two positions and their derivatives will be exploited as datasets to train the neural network and, in the end, to reach a more physiological shape of the pulse wave than can be reached by a manual setting.
