The uniform numerically-characteristic technique is proposed for the elastic wave propagation problem solving in thin piecewise and homogeneous isotropic shells with various geometrical and physic mechanical parameters. The influence of geometrical parameters of a shell parts on their unsteady movement caused by the strain pulse where shell deflections are commensurable with its thickness were investigated. The mathematical finite-elements model is made for viscous elastic deformation of composites. General solution technique for contact interaction problems is developed under different contact conditions and non centre loading of complex parts. The concrete problems are solved. The approach is worked out for torsion problems of rod with polygonal cross section. Fractal generalization of energetic fracture criterion is received. Programs are worked out. The results could be used in engineering.
