The method discussed below is based on considerations of the strain energy density variations near notches. Several examples concerning V-notches have been analysed to validate the concept. Finally, the problem associated with the analysis of sharp notches and cracks is discussed in terms of the ...
strain energy density ratefactorFunctionally graded coating (FGC) has been widely used in severe conditions for its excellent mechanical characteristics compared with pure coating material. The graded component in the FGC can be described by specified local volume fraction rules of coating material. In...
150,153 Nevertheless, the creep sensitivity to the initial dislocation density is significantly lower than the growth sensitivity to the initial dislocation density.171 On the other hand, the grain size does not seem to have a significant effect on the creep strength in the range from 1 to 70...
Nonlinear time-temperature-dependent finite element analyses are performed to determine the shear stress, shear creep strain, shear stress and shear creep strain hysteresis loops, and creep strain energy density of the corner solder joint. The thermal-fatigue life of the corner solder joint is then...
(strain-gauge sensor) and slip-velocity data (motor) as digital voltage values. The program uses these values to calculate the ‘PDE = Effective power density’ (blue squre), and compared it to the requested PD (blue square ‘Is effective PD = Requested PD?’). Depending on ...
The distribution of the von Mises stress and strain energy density in the regions near the interfaces of γ /γ' phases were calculated by the elastic-plastic stress-strain finite element method (FEM), and the influences of the applied stress on the von Mises stress distribution and the ...
The presence of small spheres, with their larger energy density, increases the yield stress of the system, thereby improving the quality of the rheological data while still allowing for the simultaneous observation of the large spheres with confocal microscopy16,17. The rheological and confo- cal ...
Moreover, its hardness shows a larger sensitivity to strain rate and the film with the higher hydrogen content also exhibits a larger and slower creep deformation when subjected to a step-loading experiment. The creep data compares well to the Burgess model and we discuss the influence of Van ...
FEA simulation results showed that different models lead to similar creep strain and creep strain energy density, and similar fatigue life was predicted based on results from these four creep models [29]. Among steady-state creep models, hyperbolic sine model is commonly implemented for electronic ...
In SRP method, the total inelastic strain is considered to consist of time-independent plastic and time-dependent creep strain with four possible combination cycles.
