The theoretical analysis of stress-strain state of materials with gradient structure


The analysis of the stress-strain state of a material with a hardened layer obtained when exposed to concentrated energy fluxes, using matrix algorithms of the theory of elasticity by contact loading is implemented. The dependences of the normal and tangential stresses from the longitudinal dimensions of the sample in the transition zone between the hardened layer and the matrix are found. It is shown that the resulting stresses are compressive and do not exceed the tensile strength of materials.
