摘要
讨论了弹塑性有限元理论和大型有限元软件ANSYS在钢筋混凝土结构中的应用,探讨了弹塑性有限元理论中的单元类型、材料本构关系和有限元模型的建立以及在ANSYS中的实现,对边界条件的处理、求解精度和加速解的收敛性等问题给出一些改进措施,最后通过与试验值比较,验证了ANSYS仿真结果的可靠性。
The paper discussed the elastic and plastic finite element theory and the large software - ANSYS applied to the reinforced concrete structure. The paper discussed the element types in the elastic and plastic finite element theory, the material and the structure relationship, the establishment of the finite element model and the application of the ANSYS. The paper provided some improved measures for the boundary condition processing, solution precision and convergence. Finally, the paper, in comparison with the test values, had certified the reliability of the ANSYS simulation results.
