Abstract—
Based on the law of elastic unloading under conditions of elastic-plastic contact deformation of the friction surface of a part by a spherical indenter, an analytical dependence for the nondestructive determination of the Poisson ratio based on the law of elastic unloading under conditions of elastic-plastic contact deformation of the friction surface of a part by a spherical indenter is obtained. To implement the method, it is necessary to have data on the magnitude of the contact load on the indenter, the elastic properties of the indenter material, the diameter of the residual dint on the surface of the part, and the total value of elastic reshaping of elastic-plastic dint at surface of part and deformed elastically surface of spherical indenter in the center of contact. The proposed method allows both to carry out scientific research of elastic properties of friction surfaces and to use it in production conditions using existing equipment. Experimental verification of the method was carried out on various materials of parts made from ferrous and non-ferrous metals and showed that its error does not exceed 5%.
