已知负载超过其安定极限的滚子会经历其表层的累积塑性剪切。Merwin和Johnson（1963）对这种变形的近似分析与实验结果非常吻合，但Bhargava等人（1984）最近进行的有限元计算预测了更大的变形。本文对这种差异进行了研究，并提出了另一种分析方法，以支持有限元分析。
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.
