Abstract
This paper deals with two-dimensional rolling-sliding contact problem on an elastic half-space containing multiple growing surface cracks located close to each other. Rolling-sliding contact is simulated as Hertzian-distributed contact load with normal and shear components. The problem is solved using complex-variable techniques and is reduced to multiple 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 the frictional coefficient, crack angle and crack length on the results are considered.
