Abstract

For the purpose of studying the sheet forming process of thin- walled structures a specific finite element method has been developed based on plane strain shell elements for cross-section analysis with elastic-plastic behaviour. The contact and friction boundary conditions are imposed by moving shaped tools using the exterior penalty method and cold roll-forming is considered. INTRODUCTION As we are concerned by sheet forming process and unloading problems in order to get residual stresses the elasto-plastic model is used for numerical calculations of sheet metal forming presented in the paper instead of the simpler rigid-plastic model. The standard incremental implicit approach based on incremental
