中文摘要:船体板在波浪载荷下会受到交变拉/压作用,因此必须考虑疲劳对船体板剩余寿命的影响,尤其是对含点腐蚀船体板剩余寿命的影响。本文对单点腐蚀船体板剩余疲劳寿命进行了数值计算,结果表明:使用二次单元对含蚀坑船体板应力集中系数的计算误差不超过10%,而使用线性单元误差可达40%;蚀坑直径对单点腐蚀船体板疲劳寿命的影响不大,而船体板剩余疲劳寿命随蚀坑深度的增大而迅速减小。可见,对于点腐蚀钢板的应力集中计算,使用而二次单元比使用线性单元更准确;蚀坑深度对单点腐蚀船体板剩余疲劳寿命的影响比蚀坑直径的影响更为显著。
英文摘要:Hull plates will be subjected to alternating tension/compression under wave load, so the influence of fatigue on the residual life of the hull plate, especially on the residual life of the hull plate with pitting corrosion, must be considered. In this paper, the residual fatigue life of single point corrosion hull plate is calculated. The results show that the error of stress concentration coefficient of hull plate with corrosion pit is less than 10% and the error of linear element is up to 40%. The diameter of corrosion pit has little effect on the fatigue life of single point corrosion hull plate, but the residual fatigue life of hull plate decreases rapidly with the increase of the depth of corrosion pit. It can be seen that for the stress concentration calculation of point corrosion steel plate, using quadratic element is more accurate than the linear element, and the effect of pit depth on the residual fatigue life of single point corrosion hull plate is more significant than that of pit diameter.
