Rigid plastic material models are suitable for modeling metal forming processes at large strains where elastic effects are negligible. A distinguished feature of many models of this class is that the velocity field is describable by non-differentiabl

Single point incremental sheet forming (SPIF) is a process of manufacturing parts that leads to low prices of manufactured parts and high productivity. However, surface finish and forming time are responses that still need to be optimized to get bett
