Amongst the wide range of metal foam applications, the heat exchange industry is the most notable. Heat exchangers are devices that transfer heat from one medium to another that in most cases the two media are air and water. Specifically, aircooled heat exchangers consist of a number of water tubes to transfer the heat between the pumped air and the flowing water through the tubes. Covering the...

This analysis considers the flow of a highly viscous Newtonian fluid in a reticulated, elastomeric foam undergoing dynamic compression. A comprehensive model for the additional contribution of viscous Newtonian flow to the dynamic response of a reticulated, fluid-filled, elastomeric foam under dynamic loading is developed. For highly viscous Newtonian fluids, the flow in the reticulated foam is...

The paper introduces a new alternative towards fabrication of auxetic metamaterials (materials with negative Poisson’s ratio) controlled by geometric transformations. These transformations are derived from the theory of small (infinitesimal) elastic deformation superimposed on finite elastic deformations. By using this theory, a cylindrical region filled with initial deformed foam is transforme...

Foam composite panels made from hybrid fillers are materials developed to have low density with high mechanical properties. This work focuses on improving the properties of epoxy-based foam hybridized by combining hollow glass microspheres (HGM) and nanoclay. The HGM content was varied 1 wt.% 3 in composites panel, while nanoclay 5 each HGM-filled series these were fabricated using a convention...

This paper examines the behaviour of circular steel tubes infilled with concrete incorporating recycled rubber particles. The rubberised concrete-filled are tested under lateral cyclic deformations and without co-existing axial loading. A detailed account tests on twelve specimens is provided together complementary material section tests. replacement ratio varied up to a relatively high value 6...
