elasticity, plasticity, tension, heterogeneity, biaxial stretching.

Various options of inclusions have been studied in works [5–8]. The elasto-plastic and deformed conditions of the anisotropic plane weakened by the opening supported with eccentric circular inclusion are considered in works [2,3]. Biaxial stretching of an elasto-plastic plate with a circular opening in case of transmitting anisotropy is investigated in work [4]. In work [5] the elasto-plastic condition of the plane with the circular opening supported with the elliptic inclusion displaced only in one direction concerning the center of an opening has been considered. In the present article work is generalized [5]. It is supposed that the circular opening is strengthened by the elliptic inclusion displaced in two directions concerning the center of an opening. The case of flat deformation is considered. The border of an elasto-plastic zone is defined, influence of non-uniform inclusion on a plane tension is considered.
