If the failure mechanism of structural components made from composite material is optimally used in automobiles, they can absorb far more energy than equivalent steel components. Within the EUREKA research project CARMAT 2000 such elements were investigated at BASF AG Ludwigshafen. The major goal was to develop an exchangeable crash element for low velocity impact. The contribution presents an overview over recent progress in the numerical simulations of composite damage. Due to the limited space the paper concentrates on computational aspects for the crashworthiness analysis of laminated composite shell structures under low velocity impact. Numerical results for the axial crushing of composite tubes with different cross sections are presented and compared to experimental investigations. The analytical models developed can be further used for design studies.
