Analysis of a dynamic thermo-elastic-viscoplastic contact problem

Dynamic Frictional Contact for Elastic Viscoplastic Material

Using a general theory for evolution inclusions, existence and uniqueness theorems are obtained for weak solutions to a frictional dynamic contact problem for elastic visco-plastic material. An existence theorem in the case where the friction coefficient is discontinuous is also presented.

Numerical Analysis of a Frictionless Contact Problem for Elastic-Viscoplastic Materials

We consider a mathematical model which describes the unilateral quasistatic contact of two elastic-viscoplastic bodies. The contact is without friction and it is modeled by the classical Signorini boundary conditions. The model consists of an evolution equation coupled with a time-dependent variational inequality. It has been shown that the variational problem of the model has a unique solution...

The Eshelby Problem for Elastic Viscoplastic Materials

Micro-macro schemes contain two important steps. First, the localization process must link the fields inside the inclusion to those applied in the infinite matrix. Secondly, an averaging process is used to derive the macroscopic behavior. For elastic viscoplastic materials, there is no exact solution for the first step. In this work, we adopt the interaction law proposed in [2]. By comparison w...

Solution of a semi-coercive contact problem in a non-linear thermo-elastic rheology

Thermo-Elastic Analysis of Non-Uniform Functionally Graded Circular Plate Resting on a Gradient Elastic Foundation

Present paper is devoted to stress and deformation analyses of heated variable thickness functionally graded (FG) circular plate with clamped supported, embedded on a gradient elastic foundation and subjected to non-uniform transverse load. The plate is coupled by an elastic medium which is simulated as a Winkler- Pasternak foundation with gradient coefficients in the radial and circumferential...
