复合材料结构分析挑战及samcef composites解决方案(201507)

1.
复合材料的介绍文档 7-1

挑战： 1.Composite materials and metals are completely different

2.Their use requiresdedicated design and analysis approaches

3.With classical analysis approaches (analytical or linear)

4.Composites are thin-walledstructures

5.Damage appears in composites, even when unexpected

6.Damage also present for static cases, notonly for fatigue

7.Damage is sometimesinvisible, e.g. Barely Visible Impact Damage (BVID), so this may be verydangerous if ignored

8.Working with compositesimplies the management of a very large amount of design parameters (much morethan for metals)

9.Physical tests areexpensive, sometimes difficult to conduct and numerous
