The method and algorithm for analyze nonlinear deformation and stability for a wide class of thin elastic shells of heterogeneous structure for traditional and composite materials is developed. It is proposed modeling technique in the layer structure of a finite element unidirectional fiber composite material, which elastic constants are determined by its micromechanical parameters; 2. New calculation methods of the natural oscillations of shell structures of regular and irregular structures are designed. Generalizing algorithms are proposed. These algorithms is accurately described the real properties of objects and allow us to calculate the action of such structures dynamic loads, including pulse; 3. The method and algorithms for determining of 3D stress-strained state and fracture mechanics parameters under dynamics loading was designed using semianalytical finite element methhods.
