| 摘 要： | 采用预制缺口的舰体结构试样,对舰用907A钢在拉伸疲劳载荷作用下的裂纹扩展规律进行了高频疲劳试验研究,得出在拉伸疲劳载荷作用下舰体结构的裂纹扩展规律,模拟了舰船在航行时波浪交变载荷对舰船结构的破坏作用,试验结果对预报破损舰船在波浪中航行时的裂纹扩展情况具有参考作用。

| Abstract: | By using hull structure specimens with V type gap,the rule of high-frequency fatigue crack growth rate for 907A marine structural steel are investigated experimentally under extension fatigue loading,which is reasonably similar with the sailing condition of ships in waves.The experiment results may provide guide for predicting crack growth.situation of the warships. |
