Résumé

The solution is given of the thermoelasticoplastic problem about slide of a heavy layer from an inclined plane under heating. The creep effect is stipulated to the development of a viscoplastic flow at the cost of a dependence from the temperature of the material layer yield strength. Within the theory of large deformations the law of the propagation of elastoplastic boundary is indicated, stresses, strains and strain rates are calculated both in the area of thermoelastic deformation and in the area of flow.

Détail

Keywords: elasticity, plasticity, viscosity, thermal conductivity, large deformation.
