基于关于临界能量释放率、弹性模量和屈服极限等参数的计算结果作为输入参数,辐照前的屈服极限取实验值,通过有限元软件ABAQUS分析了辐照前后FeCrAl包壳拉伸断裂行为差异,并建立了FeCrAl包壳管几何模型。
Based on the calculation results of parameters such as critical energy release rate, elastic modulus and yield limit as input parameters, the yield limit before irradiation was taken as experimental values, and the difference in tensile fracture behavior of FeCrAl cladding before irradiation was analyzed by finite element software ABAQUS, and a geometric model of FeCrAl cladding tube was established.
