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, K-I and K-II, 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 K-I and K-II for arbitrary geometrical and loading conditions, is developed. The pro-ram is also applicable to the study of fretting fatigue crack propagation mechanism. (C) 2003 Elsevier Science Ltd. All rights reserved.
