Dynamic response and energy absorption of functionally graded porous structures

Influence of anisotropic grains (platelets) on the microstructure and uniaxial compressive response of ice-templated sintered alumina scaffolds

This study investigates the effects of the size of hollow glass microspheres (20 μm vs. 40 μm) and composition on the energy absorption capacity of the silicate glass foams under both the quasistatic (∼10^(−3) s^(−1)) and high-strain rate (∼10^3 s^(−1)) loading conditions. These measurements revealed that while the size difference of the hollow glass microspheres and the foam composition have negligible effects on the uniaxial quasistatic response, their effects were significant under the dynamic loading conditions. The results suggest that the smaller glass microspheres (20 μm) dominated the dynamic behavior of the glass foams in comparison to the larger glass microspheres (40 μm), leading to a significant increase of the energy absorption capacity of the 20 μm-based glass foams at high-strain rates. Glass foams exhibited energy absorption capacity of about 54 kJ/kg under the dynamic loading that is greater in comparison to that of the typical metallic and syntactic foams.

A Comparison of Microstructure and Uniaxial Compressive Response of Ice-Templated Porous Alumina Scaffolds Fabricated from Two Different Particle Sizes

Preparation and characterization of hollow glass microsphere ceramics and silica aerogel/hollow glass microsphere ceramics having low density and low thermal conductivity

Optimization of cellular solids for energy absorption

Apparatus, systems, and methods of measuring relative pressure based on the displacement of a Cartesian diver are provided. Within the system, various designs of divers, as well as a variety of measurement methods implementing such systems and apparatus, are illustrated. The systems and methods described herein are directed to precise pressure measurements traceable to the SI through the vertical displacement of a ludion within a two fluid system. The system is selectively optimized to ensure the buoyancy and mass of the ludion as well as the density of the gases and fluids involved are known and controlled.
