| 中文摘要: |
| 板料成形过程是涉及几何非线性、材料非线性和边界条件非线性等的多重非线性问题。介绍了板料冲压成形CAD数字化分析所涉及到的基本理论——非线性弹塑性材料的本构关系、板壳成形单元模型、接触问题、有限元方程及求解。 |
| 英文摘要: |
| In sheet metal forming, there are several nonlinear problems, including geometry non-linear, material non-linear and boundary condition non-linear. Several principles in sheet metal forming simulation such as material model, element model, contact model and finite element equation are summarized in this paper. |
