This paper presents a precise and cost effective numerical simulation approach of a corrugated composite crush web axial crushing that can be used in the design phase. Intra-laminar and inter-laminar failures of composite laminates were considered to improve the accuracy of a simulation and the complete laminate properties of laminate was adopted to reduce computation time. To validate the proposed simulation approach, specimens were fabricated and experimental study was carried out. The results of the simulation showed that very good agreement with the experimental data quantitatively and qualitatively and a significant decrease in the computation time.
Keywords : Axial crushing(압축파손), Impact energy absorption(충돌에너지 흡수), Finite element analysis(유한요소해석), Corrugated composite crush web(주름진 복합재 크러쉬 웹)
