Shaping of Aluminum Foam Using Point Group Mold

Manufacture of Aluminum Closed-cell Foam by ARB process using CaCO3 as the blowing agent

Metal porous foams have been eliciting much interest in recent years due to their high capacity of energy absorption. The characteristics of the pores in these materials play an important role on their energy absorption capability and other properties. This study reports the fabrication of aluminum closed-cell foams by accumulative roll-bonding (ARB) technique using calcium carbonate (CaCO3) as...

Multi-objective Crashworthiness Optimization of the Aluminum Foam-filled Tubes

In order to reduce both the weight of vehicles and the damage of occupants in a crash event simultaneously, it is necessary to perform a multi-objective optimization of the automotive energy absorbing components. In this paper, axial impact crushing behavior of the aluminum foam-filled thin-walled tubes are studied by the finite element method using commercial software ABAQUS. Comparison of the...

Modeling the Effects of Mold Topography on Aluminum Cast Surfaces

The air-gap nucleation time, the stress evolution and the solid shell growth pattern are examined for different mold topographies to illustrate the potential control of aluminum cast surface morphologies during the early stages of solidification using proper design of mold topographies. The interaction between heat transfer and deformation during the early stages of solidification is considered...
