In recent years, the phase-field method has attracted a lot of attention and emerged as one most efficient tools for modeling fracture phase transformation. The is based on regularization discontinuities which allows resolution complex problems using classical numerical methods. A multiphase-field model essential describing crack propagation in non-static heterogeneous materials still missing. ...

Electronic power modules devices are paramount components in the aeronautical, automotive and military applications. The solder layers are the most critical parts of the module and are usually subjected in their whole life to complex loading conditions. To improve the design task, realistic thermoelastoviscoplastic and lifetime prediction models which can describe efficiently the deformation-da...

In this study, the effects of random laminate misalignment on macroscopic and microscopic elastic/viscoplastic behaviors ultrafine plate–fin structures are statistically investigated adopting Monte Carlo simulation. To end, a multiscale method that analyzes elastic–viscoplastic behavior with both macroscopically microscopically is proposed based homogenization theory for nonlinear time-dependen...

Abstract The subject of the study is deformation oxygen-free high conductivity copper. copper sample given in form a foam. undergoes an impact into elastic wall. strain rate hardening effect investigated. numerical model open-cell foam skeleton prepared framework peridynamics method. dynamic process compression with different velocities simulated. It has been found that essential for load-carry...
