摘要
针对三维体积成形有限元数值模拟边界界面接触问题 ,提出引入边界摩擦与滑动约束的矩阵变换法 。
Pointing at the problem about boundary contact constraint of FEA numerical simulation of 3D massive forming, matrix transform algorithm has been proposed and numerical experiment and FEA simulation for upsetting formation of spur gear have been completed.
