STATIC AND DYNAMIC AXIAL COLLAPSE OF FIBREGLASS COMPOSITE THIN-WALLED TUBES: FINITE ELEMENT MODELLING OF THE CRUSH ZONE

Explicit and implicit finite element codes have been developed for predicting the axial collapse of thin-walled structures with a reasonable amount of computer time, allowing, in this manner, such structural components to be designed and analyzed without having to build and test expensive prototypes. The present paper describes the implementation of the "implicit" finite element code MARC in the simulation of the crush behaviour of cylindrical thin-wall composite tubes under static and dynamic axial compression, in accordance with the progressive mechanism of failure (Mode I of collapse). The predicted numerical results are validated by comparing with actual experimental data obtained from quasi-static and impact tests conducted in a tensile test machine and a drop hammer rig respectively. Furthermore, for ultimate validation, load and energy absorption values from the numerical results are also compared with those analytically calculated, thereof showing good agreement. (A)
