Simulation of springback in sheet metal forming
Purpose and goal
The purpose of the project is to improve the accuracy of predicted springback in sheet metal forming. Springback is a mainly stress driven problem, i.e. the magnitude of the springback depends mostly on the stresses existing in the workpiece after completed forming. The project is therefore focused on improved material modelling, and through that on increased accuracy of the predicted springback. The influence of the modelling of kinematic hardening, yield function, elastic stiffness degradation, and elastic anisotropy will be studied.
