A study of the variations in elastic modulus and its effect on springback prediction
Source abstract
Abstract
A model is proposed in order to evaluate the variation of the elastic modulus of metallic materials due to both damage and dislocations rearrangements leading to non-linear recovery. It is an elastic plastic model with varied unloading elastic modulus and coupled with damage. This model allows obtaining more accurate prediction of material behavior, starting from a virgin state and finishing by failure. Simulations have been carried out in uniaxial tensile test and the predicted results show good agreement with experiments. The L-bending test is also simulated and the proposed model allows obtaining more accurate springback prediction.
