摘要
介绍了应用三维断裂分析软件FRANC3D(Fracture Analysis Code in 3Dimensions)进行疲劳裂纹扩展分析的相关原理,利用该程序对热壁加氢反应器堆焊层表面裂纹在疲劳载荷作用下的扩展进行了数值分析;将数值模拟结果和相关试验结果进行了对比。结果表明:数值模拟和实际表面裂纹扩展路径基本相似;在加氢反应器使用寿命范围内,用FRANC3D程序预测的裂纹扩展速率比实验值保守。
The principle of the three dimensional fracture analysis software FRANCE3D （Fracture Analysis Code in 3Dimensions） on fatigue crack growth is introduced, and the actual surface crack growth on overlay of the hot-wall hydrogenation reactor was analyzed by FRANCE3D. The results of numerical simulation were compared with that of the experiment data. The results show that the surface crack growth path obtained by numerical simulation is same to that by experiment basically; and compared with the result of experiment, the crack growth rate got by FRANC3D is more conservative than the experimental data in the service-life of hydrogenation reactor.
