摘要
拉压不同模量的材料在各类工程中广泛应用,针对该特点推导出不同模量悬臂梁的解析解,并编制相应的有限元程序,分别用两种方法进行计算,并对比误差。最后对不同模量理论计算结果与经典的同模量理论计算结果的差异进行分析,并提出对该类结构计算的合理建议。
With the applications of materials with different tension and compression modulus in various engineering, the analytical and finite element solutions of cantilever beam problems have been obtained. The errors between analytical and finite element solutions are discussed in details. Finally, the solutions with different modulus were compared with the one of same modulus, and the reasonable suggestion was given to investigate this kind of materials in structural design and application.
