Abstract
The effects of trigger geometry on axially crashing behavior of carbon/epoxy composite circular tubes were investigated. The results showed that in axial crushing experiments, among 15°, 45°, 60° of the trigger geometry, 60° got the highest crashing peak load and the lowest crashing minimum load. The morphology analysis on the crushed tubes showed that the different trigger geometry led to different crashing microstructures failure for the reason on different contact conditions during crashing processing of the circular tube. As a result, the energy absorbing characteristic was deeply influenced by the trigger geometry.
