ÌôÕ½£º 1.Composite materials and metals are completely different
2.Their use requires dedicated design and analysis approaches
3.With classical analysis approaches (analytical or linear)
4.Composites are thin-walled structures
5.Damage appears in composites, even when unexpected
6.Damage also present for static cases, not only for fatigue
7.Damage is sometimes invisible, e.g. Barely Visible Impact Damage (BVID), so this may be very dangerous if ignored
8.Working with composites implies the management of a very large amount of design parameters (much more than for metals)
9.Physical tests are expensive, sometimes difficult to conduct and numerous
