Crash analysis using continuum damage mechanics
conference paper
Light weight metals, like aluminum in a crumpling zone, absorb energy through plstic folding mechanisms. Composites on the other hand, typically are fully crushed under impact loadings. A numerical approach to crash analysis of composites based on a continuous damage mechanics model is discussed in this paper. Brittle and elasto-plastic damage models are treated. The collapse of an axiaily loaded aluminum box column as well as the crushing of an axially loaded composite box column are presented. The numerical analyses have been carried out with the crash simulation program MADYMO. Good agreement between numerical and experimental results is obtained.
