The use of lightweight metals and composites to replace heavy structural materials for military hardware and weapons systems (ships, aircraft, ground vehicles, etc.) is a new strategic consideration for defence forces; falling under Naval S&T Strategic Plans. The objectives of the workshop were to seek state-of-the-art ideas, from outside of the continental United States, in the field of low-density metallic materials and composites for structural applications, as well as modeling and simulation software tools which are capable of generating and identifying damage evolution data for health monitoring, corrosion control, life prediction and assessment of civil and military hardware systems.
