Research Focus

My main project is design of bio-inspired metal-metal or metal-ceramic composite structures for shock loading applications. The inspiration from natural materials such as bone and nacre arises from the improved strength and fracture toughness of these materials, as compared to their constituents with inferior properties. The overlying aim is to create engineering composites that are both stiff and tough. A critical factor in providing improved properties is postulated to arise from the hierarchical arrangement, and it is necessary to also study theoretical models of hierarchical assemblies of structural elements, and study what improvements such arrangements provide us for mechanical properties. On a conceptual design scale, this allows us to decide if hierarchies are useful for a certain design.
