摘要 利用数值方法研究了正交各向异性材料结构的塑性极限分析问题。基于 Hill- Tsai屈服准则 ,将塑性极限分析中的上限定理以及有限元方法运用到正交各向异性体的极限分析中 ,最终将上述问题归结为求解一个带等式约束的非线性规划问题。借助数学规划中的非线性理论 ,可构造出上述问题的直接迭代求解算法。最后给出了相关算例的分析。 The aim is to calculate the plastic limit loads of structures made of orthotropic materials. The criterion yield by Hill Tsai was used to reduce the limit loads solution to a nonlinear programming problem using the upper bound analysis of plastic limit theory and the finite element method. The nonlinear theory of mathematical programming was used to develop a direct iterative algorithm. Some examples are given to illustrate the validity of the method. The results show the method can facilitate the design and application of orthotropic structures.
