This has slowed their widespread application to thin, damage tolerance-critical primary structures such as fuselage pressure cabin skins. Therefore, impact tests were performed to determine the impact characteristics of Fibre Metal Laminates (GLARE and ARALL). Comparative low and high velocity impact tests were performed on monolithic aluminium, Fibre Metal Laminates, and carbon thermoplastic composites. Additional impact tests were performed on monolithic aluminium and ARALL specimens under tensile loading.

Chen and co-workers investigated the plastic collapse of sandwich beams based onaluminium face sheets bonded to an aluminium foam core [3]. Here, it was found that the thickness of the foam affects the shear strength of the core. ...

A three-dimensional geometrically correct finite element model of the honeycomb sandwich plate and a rigid impactor was developed using the commercial software, ABAQUS. This discrete modelling approach enabled further understanding of the parameters affecting the initiation and propagation of impact damage. Strain-hardening behaviour of the aluminium alloys and the honeycomb core density were shown to affect the impact response. In addition, the impulse-momentum equation was incorporated into the energy-balance model, so that the impact force and deflection histories could be determined as well.
