Abstract
The purpose of this study is to study the applicability of Discrete Ply Modeling (DPM) to crushing of composite tubes and to study the effect of stacking sequence and trigger geometry on the Specific Energy Absorption (SEA). The model was first validated with experimental results after which various stacking sequences were simulated to optimize it with an aim to increase the SEA. The stacking sequence [90/02/90/03/90/0/90] performed the best in terms of SEA value. As a result, the confidence of the DPM has been proven for some draping sequences but seems to be less confident to simulate the trigger effect.
