Abstract
The design optimization of springback in a deepdrawing process is proposed to control the final shape of the workpiece. The manufacturing process design problem is formulated to minimize the difference between the shape of the desired workpiece geometry and the final analysis result after elastic springback. The rigid die shape and the workpiece thickness are treated as design variables. A nonlinear structural problem that includes finite deformation elastoplasticity with frictional contact is solved using a mesh-free method in which the structural domain is discretized by a set of particles. Continuum-based design sensitivity analysis is carried out to obtain gradient information for the optimization efficiently. The accuracy of the sensitivity result is compared with the finite difference result with excellent agreement. The optimum deepdrawing process significantly improves the quality of the final product.
