At the first stage, the main attention is paid to the creation of new approaches and the development of the theoretical foundations of the method of static investigation of stability and frequencies of shells of an inhomogeneous structure with allowance for the prestressed state under complex thermal force loading; the method of taking into account the imperfections in the shape of shells in analyzing the stability and strength, analyzing the existing and constructing a new system of computational equations to model the dynamic development of a crack under intense plastic deformation and considering changes of boundary conditions on its shores.
