| 摘 要： | 材料应变硬化、裂纹扩展阻力变化和高应变梯度场均对延性撕裂过程有重要影响。本文提出了一个综合考虑上述因素的缺陷评定方案,并将最后结果整理成工程界易于使用的评定曲线形式。 |

| Abstract: | Material strain hardening, crack growth resistance and non-uniform loaddistribution have significant effects on the ductile tearing processes. A defect assessment procedure incorporating above features is proposed in the present paper, with the final appearance of "design curves" to facilitate engineering applications. |
| Keywords: | defect assessment strain hardening crack growth ductile tearing process theoretical resistance curves. |
