Modern industrial standards require advanced constitutive modeling to obtain satisfactory
numerical results. This approach however, is causing significant increase in number of …

In recently proposed thermo-elasto-viscoplastic material model for metals, the damage is
described by the second-order tensor, called microdamage tensor to express the …

In the paper, the numerical simulation of Nowacki's double shear test in the framework of
recently proposed viscoplasticity theory for anisotropic solids is presented. The numerical …

Some aspects of numerical analysis of problems related to high strain rates with thermal
effects are considered. The attention is focused on constitutive modelling that describes the …

The role of thermal stresses, understood as stresses introduced by a uniform or nonuniform
temperature change in a body which is somehow constrained against expansion or …

The subject of objective rates in continuum damage mechanics is under consideration. It is
shown that by changing the definition of the objective rate in constitutive theory, one obtains …

In the paper the material model for metals and its numerical applications are presented. The
material model is stated in terms of continuum mechanics, in the framework of the …

Within this document, recent achievements of the Perzyna-type viscoplasticity theory for
metallic materials subjected to extreme loading are considered. The complexity of the …

The problem of modelling extreme dynamic events for metallic materials including strain
rates over 10 7 s-1 and temperatures reaching melting point is still vivid in theoretical …
