摘要：

Experiments are described in which records were obtained of the forces and deformation during the life cycle of the interaction of model wedge-shaped asperities of similar hardness and geometry. The results show that the asperities moved past each other by a combination of plastic deformation of the asperities and sliding at their common interface. It appears that the fracture process which in previous work has been assumed to end the cycle did not occur. Slipline field models are presented to describe the deformation and good agreement is shown between stresses and velocities calculated from the slipline fields and those measured experimentally.
