Digital cellular solids : reconfigurable composite materials
Digital materials are comprised of a small number of types of discrete physical building blocks, which assemble to form constructions that meet the versatility and scalability of digital computation and communication systems. This work seeks to demonstrate the applicability of a digital material …

On the quasi-static and dynamic crushing of random foams
Lightweight cellular materials such as foams exhibit excellent energy absorption characteristics and are widely used for impact mitigation in a variety of applications. In this study a modeling framework is developed in order to investigate the crushing behavior of Al-alloy open-cell foams under …

Structural Design Inspired by the Multiscale Mechanics of the Lightweight and Energy Absorbent Cuttlebone
… structural model for designing low-density cellular ceramics with high stiffness and damage tolerance. Cuttlebone is highly porous (porosity ~93%) and lightweight (density less than 20% of seawater), constructed mainly by brittle aragonite (95 wt%), but capable of sustaining hydrostatic …
