viscocity, plasticity, rotating disk, finite difference method

Elastoviscoplastic deforming of rotating thin disk under plane stress state is considered. Strains in the disk are assumed to be small and additively split up into elastic and viscplastic parts. Stresses are determined by elastic strains using Hooke’s law. Generalized Mises criteria considering viscosity of material is used. System of differential equations is solved by finite difference method. Obtained results of numerical computations are illustrated by figures.
