We propose an algorithm for the efficient parallel implementation of elastoplastic problems with hardening based on the so-called TFETI (Total Finite Element Tearing and Interconnecting) domain decomposition method. We consider an associated elastoplastic model with the von Mises plastic criterion and the linear isotropic hardening law. Such a model is discretized by the implicit Euler method i...

A nonconventional application of worm gears exploits the irreversibility these power transmission devices in order to realize fast emergency braking. This can be used secure lifting devices. limiting factor design instantaneous braking systems is residual deformations worm/wheel contacting teeth, due impact between them at each stop. The prediction displacements requires solving an elastic–plas...

Contact thermal resistance is an important indicator of the efficiency heat transfer between contact interfaces.The interfaces superalloy GH4169 in high temperature was investigated byusing ANSYS. The real surface morphology obtained with optical microscope, and its modelwas reconstructed Based on theory structural mechanics, elastoplastic deformation microstructure interface simulated, analyze...
