又一个简单的优化小例子， PS. 某人答对了结果 😆 。 【1】Midas Gen Model 【2】Midas2Abaqus Model 【3】Abaqus Model 【4】Optimization Results 优化目标：刚度最大化。 约束条件：体积优化 30%。 最终结果是一个三角形。 微信公众号 ( Wechat Subscription) 欢迎关注 “结构之旅” 微信公众号
做个简单的优化小例子，后续有时间继续再做深入研究吧。这些都是拓扑优化届最初级最初级的小例子。很多书本都可以看到。 先从最简单的拓扑优化开始。后续陆续分享一些实际工程的优化案例，贴近工程的一些优化思路及软件开发应用案例。 【1】Midas Gen Model 【2】Midas2Abaqus Model 【3】Abaqus Model 【4】Optimization Results 优化目标：刚度最大化。 约束条件：体积优化 50%。 (1) Step 5 (2) Step 10 (3) Step 25 (4) Strain Energy 到25步后，结构基本稳定。可以看出优化后的结构的轮廓。 后续再继续深入研究。 微信公众号 ( Wechat Subscription) 欢迎关注 “结构之旅” 微信公众号

结构弹塑性分析可以较好地反映结构的薄弱部位。大震弹塑性分析和小震设计、中大震拟静力分析具有一定的可比性。如图是YJK的拟静力楼板应力分析结果及ABAQUS大震分析的损伤结果，弹塑性分析反映了结构的薄弱部位。

ABAQUS 做整体分析比较花时间，计算也需要花很多时间，因此，每个过程均需要十分细心，因为错了从来时间成本太大。 不管是前处理建模，还是后处理分析，还有超限文本撰写，都应该是建立在对结构理解的基础上，不能论文一个操作员，能简化，能提高效率的地方就要提高效率，尽量把更多时间用在把握和理解结构机理、结构特性、建立结构概念基础上。
