复合材料铺层次序优化怎么做？

压力山大

我已经优化计算出了复合材料层合板的45,0，-45,90四个铺层方向角的铺层比例，看一篇论文说optistruct可以做铺层顺序优化，但是帮助里没有具体的例子，我试着用了用composite dshuffle模块，能优化，但是没有结果，这是怎么回事？有哪位大神用过optistruct做过铺层顺序优化啊？小弟感激不尽

在帮助里有个复合材料优化的教程，对照看下，应该么有什么问题~

我看过了，没有用，那是自由形状优化的例子，只能优化出单元厚度，不能优化铺层顺序，哪位用optistruct做过啊？

请问大神，现在做出来了吗？

可以去altair官方百度网盘找复合材料的优化教程，还有教学视频

optistruct复合材料优化分三步走：
自由尺寸优化，尺寸优化，铺层顺序优化

官方解释如下：
Composite Optimization
OptiStruct offers a comprehensive optimization package aimed at simplifying the design of
composite structures. This package includes the following optimization phases and associated
techniques:

Phase I – Concept.
Free-sizing optimization is used to generate design concepts, while only considering
global responses and optional manufacturing constraints.

Phase II – Dimension.
Sizing optimization – with ply-based modeling – is performed to control the thickness of
each ply bundle, while considering all design responses and optional manufacturing
constraints.

Phase III – Sequence.
Ply-stacking optimization is applied to determine the detailed stacking sequence, again
while considering all behavior responses and manufacturing constraints.
