One plasticity model for problems of plastic metal working
V. M. Greshnov Ufa State Aviation Technical University, Ufa, 450000, Russia
Abstract:
Scalar and tensor models of plastic flow of metals extending plasticity theory are considered over a wide range of temperatures and strain rates. Equations are derived using the physico-phenomenological approach based on modern concepts and methods of the physics and mechanics of plastic deformation. For hardening and viscoplastic solids, a new mathematical formulation of the boundary-value plasticity problem taking into account loading history is obtained. Results of testing of the model are given. A numerical finite-element algorithm for the solution of applied problems is described.
Keywords:
plastic strain, plasticity theory, loading history, physico-phenomenological approach, hardening solid, viscoplasticity.
