Defence R&D Valcartier (DRDC-V) is performing studies on the effects of anti-vehicular blast mine on armoured vehicles with the objective of demonstrating mine protection technologies on Canadian Light Armoured Vehicles (LAVs). In this research program, DRDC-V is investigating materials to protect the occupants of the LAV. Polymeric composite laminates are being considered for some applications and a robust numerical analysis tool is required to assist in the design of these structures. The work carried out at UBC supports the ongoing research at DRDC to provide lightweight blast mine protection for LAVs and other military vehicles. Currently, most LAVs have either no underbody protection against buried mine threats or rely on deflecting the blast or heavy metal plates to defeat the threat. Since it is critical for military vehicles to maintain their mobility, the lighter-weight alternative offered by composite materials are promising. FRP composites are capable of absorbing large amounts of energy through various damage mechanisms but very little research has been conducted on how to maximize blast energy absorption in composite plates. The current project primarily deals with the development of the numerical analysis framework for structural modelling of composite laminates subjected to intense impulsive loads such as blast loads. This work was preceded by two other related projects awarded to the USC Composites Group in 2002 and 2003 that dealt with experimental blast-load
