creep, elasticity, residual stress, swarm intelligence method, zero-order optimization.

The present study is concerned to the optimization problem of loading pressure computation by the prescribed displacements vector. The mathematical model of finite creep and elastic strains is used. The problem for the deformable material in the vicinity of microdefect was considered. Integro-differential equations for the external pressure, irreversible deformations and displacements were derived. The optimization algorithm for this problem was proposed. The optimal strain-stress state parameters were computed and analyzed.
