ABSTRACT

CFRPs are widely used in the automobile industry and civil engineering applications. However, the structural behaviour of CFRP-wrapped steel hollow sections under axial impact loading is not yet fully understood. This paper evaluates the effect of impact mass on the axial impact behaviour of CFRP-wrapped steel hollow square sections. FE models were developed using LS-DYNA explicit finite element code and validated using existing experimental data. The axial impact behaviour of the tubes was evaluated by studying the responses to peak impact force, axial deflection and energy absorption. Appropriate results are presented and the trends discussed.
