With rollers as elastic bodies and workpieces as elastoplastic bodies, the rolling problem can be viewed as a friction elasticplastic contact problem. With fewer assumptions in the simulation of striprolling process, a boundary element method (BEM) for twodimensional elastoplastic finite strain a...
