Abstract: The energy absorption of metal foam-filled tube wasregarded as the sum of that of metal foam and tube. Based on the straightchain plastic hinge model including the effect of eccentricity and theimproving results of Alexander model by Reddy and Wall, the deformation modeof tube was modified to reflect the effect of interaction between tube walland metal foam. Then, the expressions for the mean crushing force of staticand dynamic axial compression of metal foam-filled tube were derived. By thecomparison between theoretical prediction and experiments, the resultspredicted theoretically were found to be lower than experimental curve butagree well in the tendency, and slightly higher than the sum of averageloads of tube and metal foams. In addition, as the plateau stress of thefilling foam increases, the average compressive load of foam-filled tubeimproves linearly. This is consistent with the existed results and actualsituation, proving the rationality of the model in this paper.
