Summary

A layered composite model based on the conceptions of the 3D theory of elasticity of anisotropic solids is proposed. This model doesn't implement traditional hypotheses about the character of the stress and strain state and is exact model for some classes of boundary problems. For obtain government equations and their solution the method of initial functions is used. Particular examples of investigation static and dynamic problems of layered thick and thin plates are considered.
