The significance of the interaction of stability and damage propagation in metallic and composite panels

In general two main types of criteria are essential for the sizing of aircraft structural panels, namely, stability and damage tolerance. The way these criteria act and interact is very different for metallic and composite building blocks. While interaction of both types of criteria is relatively clear for composite parts, this is normally not the case for metallic ones. What is common for both is the fact that, if an interaction occurs, the impact is essential. The paper aims to discuss these issues.

This is a survey paper.

There is a strong mutual influence of buckling and damage in many cases.

It shows the significance of both, buckling and damage as a combined phenomenon.
