Coupled Finite Element/Meshfree Simulation of Manufacturing Problems

This paper studies the performance of a newly developed coupled finite element/meshfree tool in manufacturing problem simulation. Two manufacturing problems, a battery tray forming and an axisymmetric forging, are used for demonstration. In both problems, the coupled finite element/meshfree analysis is compared with the traditional finite element analysis. The numerical studies show that the coupled finite element/meshfree solution is as accurate as the finite element solution for the problems without mesh distortion difficulties. For the ones involving excessive deformation, the coupled method provides more reliable solutions than the traditional finite element method, but higher CPU is required.
