| Abstract: | It describes the theory of metal sheet incremental forming process,establishes the finite element model of the simulation for multiple-process incremental forming based on the ANSYS/LS-DYNA platform,obtains the distributions of thickness and distortions of the circle mesh through the LS-PREPOST and ETA/Post-Processor.It simulates three-process forming for a hemisphere workpiece,compares the result of simulation with experiment.The result shows that the simulation is feasible. |
