Impact toughness of closed cell aluminum foam
نویسندگان
چکیده
The impact toughness of closed-cell aluminum foam with various densities was investigated using Charpy impact. load history revealed an elastic region followed by a rapid drop region. peak and increase exponentially density. power exponents for the test are greater than that compressive test. Fracture analysis indicated mixed-rupture mode quasi-cleavage small shallow dimples. It can be attributed to complex state stress notched specimens elevated velocity under loading.

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...
متن کاملCompression 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...
متن کاملDevelopment of a Hopkinson Bar Apparatus for Testing Soft Materials: Application to a Closed-Cell Aluminum Foam
An increasing interest in lightweight metallic foams for automotive, aerospace, and other applications has been observed in recent years. This is mainly due to the weight reduction that can be achieved using foams and for their mechanical energy absorption and acoustic damping capabilities. An accurate knowledge of the mechanical behavior of these materials, especially under dynamic loadings, i...
متن کاملImproving the energy absorption of closed cell aluminum foams
Closed cell aluminum foams have received much recent attention as energy absorbing materials on account of their ability to undergo extensive deformation at a relatively low stress called the plateau stress. Several studies describe the improvements in energy absorption to be obtained, relative to their empty counterparts, when foam filled tubes are crushed either quasi-statically or dynamicall...
متن کاملMulti-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...
