Abstract: Parallelization of deformation-damage coupling boundary value problem solution is considered. In definition the equations of the strength we used the principle of equivalence of deformations in a real and relatively undamaged structures. Principle of real and hypothetical undamaged structure strain equivalence is applied. An iterative procedure, which feature is successive solutions of plasticity and damage problems at each iteration step, is proposed. The approach to parallelization of softening plasticity boundary value problem solution is based on the conception of generalized nonlinear structural models and on the method of decomposition.

Keywords: parallelization, structure, generalized model, decomposition, softening plasticity, boundary value problem, nonlocal plastic strain.
