FE simulation of laser-aided stamping

摘要

Laser-aided stamping of copper work-material was simulated using the FE code ABAQUS, by which temperature distributions and the stamping forces under different heating conditions were investigated. The simulation results showed that laser-heating can provide a satisfactory distribution of temperature at the shear-zone of the work-material, which will substantially reduce the maximum stamping force and enable stamping with larger aspect ratios. A high heating rate may also be achievable so that the desired stamping-temperature can be reached within a heating period that can match the requirement of industrial applications.
