The problem of calculating the degree of destruction of the fragile covering of an elastic plate with a cutout in the form of an ellipse, a triangle, a quadrangle around which can be described as a circle, a regular polygon, a semicircle, subjected to uniaxial loading. The stress state of the plate is calculated using the Kolosov-Muskhelishvili. Effect coating on the plate is taken to be negligible. Clutch cover with a plate is considered ideal and is not affected by loading.
