| 中文摘要: |
| 对精冲成形机理进行了较完整的论述，从韧性损伤的角度分析了精冲成形机理，介绍了最新的精冲损伤断裂模型。通过对精冲成形过程进行计算机模拟和精冲物理实验，验证了提出的精冲机理论述。 |
| 英文摘要: |
| The theory of fine-blanking has been given completely, and it has been analyzed from ductile fracture. The new model of ductile fracture has been introduced. It has been checked through the simulation of fine-blanking process and experiments. |
