摘要
ABAQUS是功能强大的通用有限元CAE软件,具有功能很强的非线性和前处理、后处理的功能。讨论了ABAQUS的各个模块的功能和输入方法,利用它具体求解了一个理想弹塑性材料的简支梁受均布载荷作用的问题,得到了Mises应力云图,可以明显看到塑性区的发展。用ABAQUS所得的极限载荷结果与梁的理论解进行比较完全符合,从而证明建模、分析的正确性。为进一步进行更复杂的非线性分析打下了基础。
ABAQUS is a powerful CAE software for finite element method with a strong nonlinear function. It also has a strong function of preprocess and post-process. The function of each module and the method of input for ABAQUS are discussed in this paper. A simply-supported beam made of perfectly elastic-plastic material subjected to uniformly distributed loading is analyzed by using ABAQUS. Mises stress contour plots are got and the development of plastic region is seen clearly from them. Compared with the theoretical result of beam, the limit loading from ABAQUS is rather good, which proves that the model and analysis in this paper are correct. This study lays a solid foundation for more complicated nonlinear analysis.
