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. The results are compared with the analytical and numerical solutions of other authors.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 the value of the estimated residual resources and the creep and cyclic loading in three-dimensional solids of revolution of complex shape with semi-analytical finite element method is developed. The results of analyze of determining the values of calculated and residual life of the connecting fitting high pressure are given. The influence of cyclic loading on component design life steam turbine rotor under creep conditions are carrying out.
