Design of Architectural Lattices for Ultralight and High Strength Metamaterials

At small length scales the structure of the material is organized in certain architectural fashion along with specific chemical composition. This arrangement in nature leads to extraordinary mechanical characteristics. The materials with highly ordered architectures open up the possibility of engineering the mechanical response for various practical applications including control of structural vibrations, noise, and shock mitigation. Therefore, these tunable materials are called mechanical metamaterials. We design and test these metamaterials at various length scales. Designing of materials (metamaterials) with artificial lattice for high mechanical strength at varying strain rates, novel optoelectronic interactions are the core research areas on this topic. My group activities in these areas involved both simulations and experimental validation of the designed materials.
