...Tomasz Belica; Marek Malinowski; Krzysztof Magnucki This paper presents a nonlinear approach with regard to the dynamic stability of an isotropic metal foam circular cylindrical shell subjected to combined loads. The mechanical properties of metal foam vary in the thickness direction. Combinations...

...Pedro A. Romero; Winston O. Soboyejo; Alberto M. Cuitiño Open-cell metallic foams exhibit properties desirable in engineering applications requiring mitigation of the adverse effects resulting from impact loading; however, the history dependent dynamic response of these cellular materials has...

... a material block. Metal foams made from hollow spheres offer low density with reasonably good energy absorption and high strength to weight ratios. Sintered metal hollow sphere foams have a certain volume fraction of enclosed pore space inside the spheres, but also have interstitial porosity between...

... in a metallic foam made from a rate independent plastic solid material by a switch in the deformation mode from bending to stretching of the cell walls. It is difficult to see how this mechanism switch can explain increases in plastic work by an order of magnitude or more at high velocities. This can argued...

...V. L. Tagarielli; N. A. Fleck Plastic collapse modes for clamped sandwich beams have been investigated experimentally and theoretically for the case of aluminium face sheets and a metal foam core. Three initial collapse mechanisms have been identified and explored with the aid of a collapse...

... crushing metal foams The cellular microstructure of a honeycomb is composed of a network of joined, parallel, thin-walled tubes. As a result, honeycombs are strongly orthotropic, thereby providing high mechanical performance per unit weight under shear and normal loading in the tubular direction...
