Study of crashworthiness of thin – walled aluminum square structures reinforced with ABS cores

Abstract

This study investigates the crashworthiness of thin-walled aluminum square
structures reinforced with multi-cell acrylonitrile butadiene styrene (ABS) cores. The
findings reveal a positive correlation between the number of cells within the ABS core
and both the load-bearing capacity and energy absorption efficiency of the composite
structure. Furthermore, all tested configurations exhibited a progressive and stable
deformation pattern, while undesirable curvature deformation—typically detrimental
to the performance of energy-absorbing systems—was notably absent.
