Abstract
An extensive experimental investigation was carried out to study the energy absorbing characteristics and progressive deformation behavior of unidirectional pultruded composite tubes subjected to an axial impact load. Pultruded square and circular profiles with glass-polyester and glass-vinylester combinations were used to study the specific energy absorption characteristics. Two types of triggering profiles were incorporated to investigate the effect of triggering on energy absorption. All the above combinations were investigated for three impact velocities. The effects of geometry profile, triggering and strain rate on energy absorption of composite tubes were studied in detail. A numerical simulation using finite element method was carried out to assess the energy absorption capability of composite tubes. To model the delamination between the composite plies, a new approach was adopted using cohesive elements. The progressive failure modes and crushing characteristics of the composite tubes are presented. From these studies, the composite tubes can be considered as energy absorbing members for impact applications.
