| Abstract: | A boundary element method in framework forthree-dimensional elastic-plastic frictional contact problemand solution strategies are presented. As an example, themethod is applied to analyze the plate rolling process. Theelastic contact deformation between work roll and work-piece,work-piece deformation near the edge of plate and elastic re-covery are discussed. |
