| Summary: | The crashworthiness test programs used to validate the design variants through experimental works has caused the design costs increase drastically. In the meantime, the growth in computer performance resources and new explicit finite element codes has given the opportunity to use such tools to address the design issue and the crashworthiness problem by developing numerical modelling to minimize the experimental tests costs. As a result, extensive crushing simulations for composite structures had been conducted and reported in the open literature. In this paper, it distinguished the state of the art in composite crashworthiness numerical modelling studies. Different approaches and methodologies such as modelling scales, failure modelling and architecture of crushing simulation have been studied where these factors could affected the outcomes of the simulations result for the crash analysis significantly. |
