Plastic Flow in Rollers Loaded above the Yield Point

Abstract

The plastic flow which occurs when two cylinders are rolled in line contact at loads exceeding the yield point has been examined. It has been found to consist of a circumferential movement of the surface in the rolling direction accompanied in some circumstances by radial corrugation. The resistance to rolling and distribution of pressure in the contact have been measured and the results are compared with the theoretical predictions of Merwin and Johnson in their accompanying paper (1)†.
