The investigation of the stress-strain state and vibrations of inhomogeneous anisotropic shells of complex shape in the classical and refined setting, the dynamics of discretely reinforced shell structures on elastic foundation under the action of pulsed loads was carried out on the basis of the developed numerical and analytical methods The mathematical models of the viscoelastic deformation of fibrous composites with cracks was developed. The process of slow subcritical crack propagation in these composites according to their anisotropy and of aging was investigated. The calculations of durability of fibrous composites with through cracks under internal and prolonged action of constant and external loads was carried out. The methods for studying the dynamics of a homogeneous long flexible systems, as well as with local inhomogeneities was developed basing on discrete modeling . Efficient algorithms for the numerical study of the effect on the evolution of the spatial and dynamic characteristics of flexible objects, their geometric, physical and mechanical parameters and properties of the environment were built.
