An inverse analysis approach of the Erichsen test starting from a finite element model
Source abstract
Abstract
During the deep drawing process the deformation history is different as compared to the tensile one where the constitutive equation can be identified only for small values of the plastic strain. More accurate values of the constitutive parameters can be obtained using the Erichsen drawing test. In this work we propose to use the inverse analysis principle to identify the rheological parameters directly from the Erichsen test. Results obtained for classical steel will be analyzed using an identification numerical high board (OPTPAR) automatically coupled with a commercial finite element code charged to simulate numerically the experimental test. Application to a DC03 sheet steel alloy will be presented.
