Abstract
The results of tests of quasi-static and dynamic finite thermoelastoplastic plane shear is discussed. Use is made of a new shear device in which loading and displacements are controlled in compression. Using the thermovision technique the temperature changes of the sheared paths have been registered for various shear rates. The rate-independent constitutive relations are formulated for elastic-plastic metallic solids at finite strain. The constitutive relations are considered for an adiabatic process with combined isotropic-kinematic hardening. The analogous initial-boundary-value problem as in the experiment of simple shear is formulated for finite deformations. An exceptional homogeneity of the permanent strain and temperature fields is observed in experiments and numerical simulations, over the total length of the specimens, when the strain is less than 70%. For the largest deformations the zones of strain localization are observed
