The technique for determining the parameters of a contact for indenter with the orthotropic coating on the elastic isotropic substrate

The implementation of contact for indenter with the orthotropic coating on the elastic isotropic substrate is shown. Methods of determining the exposure parameters are built on the basis of the theory developed for calculating composite coatings. To investigate the influence of material properties and thickness of the coating on the contact parameters the program, on which the calculation was performed for different coating thickness, was written. Depending on the ratio of module of elasticity of the coating and base diagrams are constructed to determine the parameters of contact (contact area, pressure and values of the indentation). The convergence of numerical solutions depending on the thickness of the coatings and the relationship of material properties is studied.
