内容简介
连续体结构的拓扑优化相对其尺寸优化、形状优化是较高层次的优化，由于其数学模型难以描述，所以被认为是当前结构拓扑优化领域中挑战性的课题。
《屈曲约束的拓扑优化（英文版）》利用ICM（independent、continuous、mapping，即独立、连续、映射）拓扑优化方法，对连续体考虑屈曲的拓扑优化问题进行了研究，建立了以结构的质量小为目标，以屈曲临界力为约束以及与位移、应力组合为多约束的四种拓扑优化模型，将优化模型转化为对偶规划，并利用序列二次规划求解，减少了设计变量的数目，缩小了模型的求解规模，并基于MSC.Patran/Nastran软件平台，利用其二次开发语言PCI，实现了全部拓扑优化程序的编制。
