Finite Element analysis of Bending Process of Steel - Plastic Laminate Sheets |
| Abstract |
Bending of the steel/polymer/steel layer laminate steel under plane strain condition is simulated by an elastic-plastic finite element program MARC. It is confirmed that the forming defects such as double-bent and slipping-off which are often found in bending of steel-plastic laminate sheets, can be simulated for different kinds of core resins exactly by using FEM. The calculated sheet geometry, load and folding angles agree well with those of the experiment. The stress state during loading and the residual stress after unloading are studied. |
