【 摘 要 】

Composites and sandwiched aluminium structures are of great importance when considering various structures of aerospace, mechanical and civil structural significance. The failure of these structures due to shockwaves and explosions are of critical importance when designing structures and hence in this study we investigate the dynamic response of aluminium corrugated sandwich panels based on the objective criteria composite layering. The result of these experiments are studied based on numerical explicit modelling of the panels and conclusions have been drawn to analyse the significance of parameters under such dynamic loads.
