The Effect of Arrangement, Density and Sample Size on Mechanical Properties of Closed Cell Metal Foam

In this study a new group of metal composite foam was demonstrated as absorption material. Closed cell metal foam was produced by casting around ceramic hollow spheres and mechanical properties were verified by uni-axial compressive test.The effect of random and ordered arrangement, density variation and sample size on mechanical properties were studied andindicated that arrangement and density significantly affect on mechanical properties and by increase density, plateau stress increased and sample size affects on plateau stress. Results of yield stresses have relatively good match by experimental formula.
