不同模量弹性力学问题研究进展

Progress of Study in Elasticity Problem with Different Moduli

简述了不同模量弹性理论近二十年来的研究进展,总结了各种工程结构分别采用两种理论进行计算的结果,认为将不同模量弹性理论应用于某些工程构件的设计是符合实际情况的。还分析了解析解与数值解的差异,尽管有限元法对不同模量弹性力学问题的求解行之有效,但寻求其解析解仍然是解决某些具体问题的难点和目标。

This paper briefly describes elasticity theory with different moduli and research progress in recent twenty years, analyzes computational results respectively from these two theories to all kinds of engineering structures and concludes that applying different moduli theory to solve some engineering components conforms to the real mechanics performance. This paper also deals with the differences between analytical solution and numerical one. Though finite element method is an effective measure to solve these nonlinear problems, seeking analytical solutions is still a difficulty and goal for some problems.
