介绍了通用有限元程序ABAQUS用于裂纹扩展的损伤模型,利用扩展有限元方法,结合损伤模型对四边简支玻璃幕墙面板进行了开裂模拟。结果表明,扩展有限元法能有效地模拟裂纹发生及扩展的过程。
The general finite element program ABAQUS for crack propagation is introduced, and the crack propagation simulation of simply supported glass curtain wall panels is carried out by using the extended finite element method and the damage model. The results show that the extended finite element method can effectively simulate the crack initiation and propagation process.
