Analysis of the Crushing of Metal/Composite Tubes Under Compressive Load


Composite tubes are effective energy absorbers in crashworthy structures and similar applications, particularly if weight is a serious concern.  However, the nature of the failure modes experienced by composite structures under crushing loads, which typically involve a combination of brittle fracture and large scale delamination, raises concerns about their general lack of structural integrity compared to more conventional metallic energy absorbers.  Various researchers addressed this concern by utilizing hybrid metal/composite tubes as energy absorbers.  Usually these are manufactured by overwrapping metal tubes with composites.  The present paper investigates a simpler form of hybrid/metal tubes in which a pultruded composite tube is confined within an outer metal tube without any bonding.  Various combinations of pultruded fiberglass tubes and aluminum outer shells were crushed, demonstrating potential improvements.  Finite element analysis was undertaken using Abaqus Explicit to further examine the crushing process, and to demonstrate the ability to simulate this class of structure as part of design studies.
