چکیده:

In this paper the effect of different hardening models on measuring springback, a common phenomenon in sheet metal forming caused by elastic strain recovery after removing the loading force, taking a benchmark of NUMISHEET’93 2-D draw bending has been discussed. The simulation of springback is modeled using the FEM code, ABAQUS 6.5 and good agreement has been found with some experimental results reported in literature. The role of hardening models on predicting field variables such as plastic strain along the sheet length and the change in thethickness of the sheet has been studied.
