On the determination of the elastoplastic state of a plane made of an anisotropic material with an elliptical hole

The elastic-plastic position of a plane made of an anisotropic material with an elliptical hole is considered. Anisotropy is the ability of a crystal to express different qualities in different directions. The presence of this quality in its simplest form can be observed only in single crystals. In polycrystals, the anisotropy of the body is basically (macroscopically) unable to be expressed in any way due to the random orientation of the microcrystals, or it does not manifest itself at all, except for special cases. With an ordered arrangement of chemical particles, the forces of interaction between them and the interatomic distances turn out to be unequal, and this is precisely the reason for the anisotropy of crystals. Another reason may be the asymmetry of its molecules. The material of the work is an integral element of the task of studying the effect of anisotropy on the stress-strain state of various structures and bodies.
