Simplified method to determine contact stress distribution and stress intensity factors in fretting fatigue

In this paper, first, a procedure to calculate the stress intensity factors, KI and KII, of the oblique crack initiated under fretting fatigue conditions is described, and secondly, a technique for determining the distributions of contact pressure and friction stress at the contact interface between plate and fretting pad is proposed. Finally, the computer program, which can calculate KI and KII for arbitrary geometrical and loading conditions, is developed. The program is also applicable to the study of fretting fatigue crack propagation mechanism.
