Grain Changing Simulation of the Copper Sheet Indented by a Conical Diamond for a micro hole forming

摘要

The method of micro hole forming indented by a conical diamond into a metal sheet based on glass substrate is an innovation. In order to solve the cracks problem of the hole edge during the indention experiment at present, the changing simulation of grain size and effective stress of the copper sheet material indented by a conical diamond is researched using the Deform 3D software with the point tracking function in this paper to reveal the mechanics changing regularity. And the mechanics of micro structure reason is analyzed with some solving method provided. The work in this paper can guide the further research with the visual simulation results without experiment cost.
