Mutual Interference of Two Surface Cracks in a Semi-Infinite Body Due to a Rolling Contact
抄録
This paper deals with the two-dimensional contact problem of a rolling rigid cylinder on an elastic half-space containing two surface breaking cracks located close to each other. The problem is solved using complex-variable techniques and is reduced to a pair of singular integral equations which are solved numerically. Numerical results of stress intensity factors are obtained for the case of two parallel cracks. The interference effects on the stress intensity factors with the distance between two cracks, and the effects of frictional coefficient and the ratio of the cracks on the results, are considered.
