摘要：

Experimental investigations into the interactions between surface pressure, tangential tractions and plastic deformations during rolling have been carried out. The most intensive plastic deformations are caused by lateral frictional forces, followed by longitudinal frictional forces. The material flow is smallest with pure rolling. In agreement with K. L. Johnson's theory for a steel with a carbon content of 0. 6% (similar to those used for wheels and rails) the shakedown limit was found at a maximum hertzian surface pressure of about 1600 N mm** minus **2.
