Effect of adhesive on the strengthening of aluminum foam-filled circular tubes

摘要

Studies of the crushing behavior of closed-cell, aluminum foam-filled aluminum and steel tubes haveshown an interaction effect between tubewall and foam filler [1, 2, 3]. The crushing loads of foam-filled tubesare, therefore, found to be higher than the sum of the crushing loads of foam (alone) and tube (alone) mainlydue to this effect. Santosa et al. [1], based on FEM results, proposed the following equation for the averagecrushing load of foam-filled square tubes of length b,
