Paper Abstract

It is very important to explore yielding, opening and developing of the crack in contact fatigue failure problems in order to understand the theory and increase the lifetime of machine parts. The numerical methods, such as finite element method are used in solving the contact problem, but for the complex bound condition and stress concentrated area the methods are limited. The scatter photoelasticity is a power tool in solving the contact problem as it can obtain the stress components and find the 3D effect conveniently and nondestructively. In order to obtain the phase value from the isodyne image with unknown order fringes accurately and automatically some isodyne image distinction methods have been developed. In this paper the frequency domination isodyne method is applied in a contact problem.
