Numerical Simulation for Cup Shell Deep Drawn by Powder Flexible Cavity

On the basis of the uniformly distributed load assumption, powder flexible cavity forming of cup shell is analyzed by MSC.Marc. The stress and strain parameters for different deformation zone are obtained. The technology is compared with rigid die deep drawing by using of point tracer method. The results prove that the forming limit can be improved and defects can be prevented when parts are formed by powder flexible cavity forming technology, which present the theoretical basis for practical application for powder flexible cavity forming technology.
