Abstract: Quasi-static axial compression tests are carried out to study the crushing behaviors of the aluminum foam filled hat sections. First, the axial compression tests of the empty hat sections, aluminum foam and the aluminum foam filled hat sections are carried out; then, based upon the test results, the crushing behaviors of the aluminum foam filled hat sections are analyzed. It is found that, aluminum foam filling can greatly increase the energy absorption abilities of the hat sections. Compared with the non-filled structures, aluminum foam filled structures need less mass to absorb the specified energy.

Key words: Aluminum foam, Crushing behaviors, Hat section
