A numerical study on the quasi-static axial crush characteristics of square aluminum tubes with chamfering and other triggering mechanisms

This paper presents a numerical study on the effect of triggering mechanism on the load-displacement characteristics and folding pattern of square aluminum tubes subjected to quasi-static axial crushing. Chamfering was the principal triggering mechanism investigated. The other triggering mechanisms included a triangular hole pattern, a geometric imperfection and combinations thereof. The study has shown that triggering mechanism can...
