Optimization of thin-wall cylindrical shells with compliant cellular-solid cores
… are often supported by a honeycomb- or foam-like cellular core, as for example, in plant stems, porcupine quills, or hedgehog spines. Previous studies have suggested that a compliant core increases the elastic buckling resistance of a cylindrical shell over that of a hollow cylinder of the same …

Design and analysis of active fluid-and-cellular solid composites for controllable stiffness robotic elements
… Specifically, meso-scale composites--composed of cellular solids impregnated with active fluids-were be designed to have controllable stiffness to take the form of a continuous body of a soft robot. This represents an improvement compared to past efforts in soft robotics, which often involved …

Effective properties of magneto-electro-elastic two-dimensional cellular solids
Two-dimensional cellular solids composed of magneto-electro-elastic (MEE) materials were studied using the finite element method (FEM). A MATLAB code was written to implement field models to determine the effective properties for this cellular solid including elastic, piezoelectric, piezomagnetic, …

Effect of composition and sintering temperature on silica-nickel oxide foams by slurry method
… Natural lightweight materials such as bone, is a cellular solid with optimized structure. The aim of this study is to fabricate silica-nickel oxide (SiO2-NiO) foams with 20 μm to 800 μm open pore size, 50% to 80% of porosity, good physical and mechanical properties. In this research, silica (SiO2) …

Design and fabrication of high power microbatteries and high specific strength cellular solids from bicontinuous microporous hierarchical materials
… power density as well as hierarchical cellular solids with controllable modulus and high specific strength. Self-assembly, electrodeposition and microfabrication enable the fabrication of microbatteries with hierarchical electrodes. The three-dimensional bicontinuous interdigitated …

Passive biomimetic actuators : the role of material architecture
… systems based on lignified, low-swelling, cellular solids enclosing a high-swelling cellulosic phase. This is the case of the Delosperma nakurense seed capsule, in which a specialized tissue promotes the reversible opening of the capsule upon wetting. This tissue has a diamond-shaped …
