Finite Element Analysis of The Deep Drawing Process of Magnesium Sheets

Abstract

This study presents a finite element simulaation of the deep drawing process applied to a 2-mm thick magnesium sheet using Simufact Forming. The forming operation was investigated under four different punch velocities, 10 mm/s, 20 mm/s, and 30 mm/s, to assess the influence of deformation speed on material response. The numerical results revealed distinct differences in stress distribution, effective plastic strain, and deformation pattern as a function of forming velocity. The simulations also produced force evolution curves along the Z direction, which demonstrated clear correlations between forming speed and required forming load. At lower speeds, material flow was more homogeneous with smoother strain gradients, whereas higher forming speeds resulted in intensified stress concentrations and more localized deformation. The analysis provides insight into the strain-rate-sensitive forming behavior of magnesium sheets and supports the selection of optimal forming conditions for improved manufacturability in lightweight structural applications.
