Development of invariant plasticity theory approach to construction of non-isothermal plastic flow models

Constitutive equations of invariant plasticity theory model with two structural parameters are presented. The method of determination of model applicability for non-isothermal cyclic loading simulation of constructional materials is described. Results of model testing on non-isothermal and non-propo...

Description
Summary:Constitutive equations of invariant plasticity theory model with two structural parameters are presented. The method of determination of model applicability for non-isothermal cyclic loading simulation of constructional materials is described. Results of model testing on non-isothermal and non-proportional loading programs for nickel base alloy IN738LC and steel 45 specimens are presented in compare with experimental results from literature.
