摘　　要：采用FAD法对某含轴向穿透裂纹的Q345R圆筒进行了断裂力学评定,并采用弹塑性有限元方法计算了裂纹尖端的J积分,为在役含缺陷压力容器安全性评价提供一定参考。By using FAD method,in this article,facture assessment for one cylinder with penetrating crack and made of Q345R was carried out.Inelastic finite element analysis was used to calculate the stress intensity factor at the tip of crack,which may be referenced in safety assessment for in-serviced pressure vessels with defects.

关 键 词：轴向裂纹 穿透裂纹 断裂评定 应力强度因子
