复合材料波纹梁盒段耐撞性的数值模拟

Numerical investigations of composite corrugated board box， subjected to crash loading, was performed with the explicit finite element code MSC/DYTRAN together with the equivalent method for material properties. The crush process, contact force-deformation curve and the data of energy absorption during the course of crash were obtained. Numerical results were compared with the experimental results presented by M.A.McCarthy, good correlation was observed. One may conclude that it is possible to analyze the crashworthiness of composite structures by using the MSC/DYTRAN together with the equivalent method for material properties.
