Abstract

The dynamic responses of a new kind of multi-structured knitted composite T-beam under transverse impact were investigated with a modified split Hopkinson pressure bar. The multi-structured knitted composite is composed of two knitted fabrics: biaxial warp-knitted fabric and weft double-faced interlock knitted fabric. The impact load-displacement curves were obtained to analyze the influences of impact velocity and flange height on the damage of the T-beam. A user-defined material behavior and critical damage area failure criterion were developed to calculate the impact damage evolution. The failure mechanisms of the T-beam with different flange height were discussed from the finite element results.
