Calculation of the stress-strain state of gear teeth made of composite and functional gradient materials

A method for determining the contact zone, stresses and displacements during the interaction of gear teeth made of composite and functionally gradient materials (FGM), based on the theory of anisotropic elasticity theory is presented. The graphs of the depth dependence of stresses on the contact surface for various materials are presented, and a good correspondence is shown for the limiting case – the isotropy of the material.
