Abstract

Rollers loaded above their shakedown limit are known to undergo cumulative plastic shearing of their surface layers. An approximate analysis of this deformation by Merwin and Johnson (1963) was in good accord with experiments, but a recent finite-element calculation by Bhargava et al. (1984) predicted much larger deformations. This paper investigates the discrepancy and presents an alternative analysis which supports that by finite-elements.
