Superplastic bonding of aluminum foam.

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...

Accumulative Roll Bonding of Aluminum/Stainless Steel Sheets

An Al/Stainless Steel/Al lamellar composite was produced by roll bonding of the starting sheets at 400 °C. Afterward, the roll bonded sheet was cut in half and the accumulative roll bonding (ARB) process at room temperature was applied seven times. As a result, the central steel layer fractured and distributed in the Al matrix among different layers introduced by the repetition of roll bonding ...

Mechanical properties of a density-graded replicated aluminum foam

The compressive mechanical properties of uniform and density-graded Al-6061 foams, produced by replication of polymer foams, are measured. hile the uniform foam shows compressive behavior characteristic of conventional (uniform) metallic foams with a near constant plateau stress, he density-graded foam exhibits a smoothly rising plateau stress. This behavior is modeled using a simple series com...

Compression and low-velocity impact behavior of aluminum syntactic foam

We report quasi-static compression and impact behavior of aluminum syntactic foams (ASF) produced by melt infiltration. Aluminum syntactic foams with relative density of 0.46 were produced using hollow alumina spheres (4.45 mm and 3.05 mm) randomly situated in a mold and two types of aluminum alloy (1100 and 6061). The impact behavior was investigated using an instrumented drop tower. We invest...
