Abstract: Aluminium foams, which may replace all the energy absorbing materials in near future, are produced by melting Aluminium alloy (LM6) containing blowing agent(s) and with continuous stirring of the melt. TiH2 is a known blowing agent for this. As TiH2 begins to decompose into Ti and gaseous H2 when heated above about 738K (465°C), large volumes of hydrogen gas are rapidly produced, creating bubbles that leads to manufacture of closed cell foam. Cellular materials like this produced foams has to be machined into pieces with desired shape for further investigation. In order to define the Compressive and impact properties of this material, LS-DYNA modeling and crashing simulation, which uniquely defines the mechanical behavior of this modified Al-MMC foam has been discussed in details.
