An elastoplastic model for calculating the residual stresses caused by the indentation of a semi-infinite solid by aflat punch is developed to allow calculation of the residual stresses left in a soft surface after it has been rubbed by a hard wedge. Despite the simplifications used, the model predicts to within 20 per cent the magnitude of the residual stresses produced by the gentle grinding of metals. It also predicts the essential features of the stress field and direction of crack propagation in some recent experiments on the sliding of steel wedges on aluminium.
