DISCRETE FE MODELING TO SIMULATE MICRO-FRACTURE

A crush zone progresses in a steady form during the crushing in fiber reinforced composite tubes when subjected to axial compression (Fig. 1 (a)). Hull [1] and Farley [2] classified the progressive failure mode into two extremes of crushing modes based on crushing morphology.
