| 摘 要： | 对作用于12CrNi3A钢的多冲过载对随后裂纹扩展的影响进行了研究。结果表明,多冲载荷下过载同样存在着裂纹扩展延迟效应,且与过载时的冲击速度有关。根据实验结果对过载延迟的机制进行了初步探讨。

| Abstract: | The writers have made a study of the effect of overload under repeated impact loads on crack propagation in steel 12CrNi3A. The result shows that under the repeated impact loads,the overload also makes crack propagation delay,and the delay is relative to impact velocity.Based on the experimental results,this paper also discusses the mechanism of overload delay. |
