| Abstract: | The article considers an elastoplastic problem for a plane weakened by an infinite number of round openings. It is assumed that the level of the stresses and the distance between the openings are such that the round openings are completely enveloped by the corresponding plastic zone; under these circumstances, the adjacent plastic regions do not coalesce. The article also considers the inverse elastoplastic problem under conditions of plane strain for an unbounded plane, weakened by a periodic series of openings. A number of communications have been devoted to periodic problems in the theory of elasticity and plasticity with an unknown boundary 1–8]. In distinction from 1–8], in which the method of perturbations was used, another method is used to solve periodic elastoplastic problems, making it possible to obtain a solution with any arbitrary relative dimensions of the region. |
