Estimation of residual stresses in metal surface layers after the roller burnishing process

The roller burnishing process is reduced to the classical problem of rolling of a rigid cylinder on a deformable half-space. Considerations are focussed on the case of high loads when a plastic wave appears ahead of the roller. The half-space is assumed to be rigid-perfectly plastic during loading and elastic during unloading. It enables one to estimate residual stresses in the rolled material. The estimations take a form of simple analytical expressions. The results are compared with the predictions made by Merwin and Johnson (1963), Pomeroy and Johnson (1969).
