【 摘 要 】

The study is devoted to the urgent question of forecasting the development of defects in the form of cracks in a two-layer elastic material, which affect its strength and durability. The results will allow us to simulate the occurrence and behaviour of the defect from the insufficient strength of the material, as well as to formulate the optimal operating conditions for the two-layer material. Given analytical expressions will let to see the effect of various parameters of the initial state on the development of a defect in the form of a crack of a longitudinal fracture.
