Aluminum foams are a novel branch of advanced materials with superior properties. Sandwich structures with aluminum foam core are good energy absorbers. In this paper, mechanical properties and energy absorption of aluminum foam sandwich panels...

functions to decrease the initial stiffness. Then, a solid plate applies loading on the cone to develop the desired deformation of the cone served as energy absorption.

In addition, some parameters such as the energy absorption E, specific energy...

% SiO2 nanocomposite makes the highest hardness. Evaluation of compressive behavior of Al-SiO2 nanocomposite foams showed that the plateau stress increases more than 3 times as the foam relative density increases from 0.09 to 0.16. Energy absorption...

impact penetration were experimentally investigated. During test, top face-sheets globally bended and tore into several pieces and so absorbed part of impact energy. Rupture and densification are two deformation modes and energy absorption mechanisms...

Thin-walled structures are used widely in engineering and industry. High strength and stiffness, low cost, very high loading capability and high energy absorbing capability are some of their advantages. When a thin-walled ...

process. Then some of them filled by a very light polymeric foam to increase their energy absorption capability. The specimens were tested under compression test between two flat parallel rigid plates under quasi-static loading. Results show that aluminum...

In this paper, the effect of adding silica nanoparticle to epoxy, silica weight percent, particle size and various combinations of epoxy/silica on Young’s modulus, yield strength and energy absorption capability of thin-walled square columns...
