The paper considers the actual problem of an assessment of mechanical characteristics of two-layer materials by nondestructive methods (a method of conical indentation). The calculation of the process of indentation into two-layer medium by the finite element method with ANSYS program. The influence of layer thickness on the parameters of the indentation is considered.
