Constitutive relations of the theory of elastoplastic processes for solving boundary problems under a plane stress state
Keywords:

Abstracts:
For the case of a plane stress state, the constitutive relations of the connection beyond the elastic limit between stresses and strains in velocities are obtained. The tracking parameter is taken to be the generalized time, which increases monotonically in the course of deformation. The presented relations with specified plasticity functionals make it possible to solve boundary value problems based on the theory of elastoplastic processes using the finite element method in velocities.
