Calculations at working conditions of these connections under tension loading was performed. A top loading elements of bolt connection was identified. Estimation of fatigue life (cycles to failure) of bolt connection was performed. The model represented results in linear mechanics. A new technique of 3D field of deformation distributions in investigated zone at plastic deformations of specimen made by composite materials. This approach makes it possible to significantly simplify experimental equipment, measurement algorithm and increase the range of fixed displacement. This paper deals with the problem of interaction of elastic waves with SH-waves defect in a plate of polymer composite material, which is placed parallel to the stress-free wafer surfaces without imposing restrictions on the depth of its occurrence.
