This work consists to study the spring back in the deep drawing of flat sheets. A phenomenological elastoplastic model taking into account the strain path change was implemented in the ABAQUS software using an implicit integration scheme. The simulations were realised on a benchmark deep drawing test designed to emphasize the spring back behaviour. A study on the influence of the process parameters was realised with the variation of blank holder force and friction coefficient between the tools and the sheet.

Investigation of advanced strain-path dependent material models for sheet metal forming simulations Article dans une revue avec comité de lecture;BALAN, Tudor; ABED-MERAIM, Farid (Elsevier, 2006)
Sheet metal forming processes often involve complex loading sequences. To improve the prediction of some undesirable phenomena, such as springback, physical behavior models should be considered. This paper investigates ...
