INVESTIGATION OF A COMPOSITE TENSILE ENERGY ABSORPTION ELEMENT UNDER STATIC AND DYNAMIC LOADING

An experimental study was conducted to investigate the energy absorption capability of a tensile energy absorber, in which a metallic bolt is continuously pulled in in-plane direction through a composite or sandwich plate, causing it to fail successively under bearing mode. The presented study addresses the influence of various parameters such as fibre and matrix material, fibre architecture and angle as well as loading rate on the specific energy absorption. Furthermore, a modelling approach for the energy absorber with Abaqus/Explicit is presented.
