AutoCAD在板料拉深成形有限元数值模拟中的应用

The use of AutoCAD in the numerical simulation of sheet metal drawing formation process by finite element method

基于 Ａｕｔｏ Ｃ Ａ Ｄ Ｒ１２ 软件， 利用其 Ａ Ｄ Ｓ系统， 开发了筒形件拉深面内变形有限元数值前后处理程序。该程序具有动态显示拉深过程中有限元网格变化及应力分布图等功能， 并对前后处理功能实现方法进行了讨论。

A tube drawing program of surface deformation was established on the software of Auto CAD R12’s system of ADS The program could dynamically show the change of the finite element net and the strain graph The article also discussed the implement of the finite element method’s forward and backward function
