Abstract
In this paper, the low-velocity impact of metal foam-filled circular tubes are investigated. Based on the quasi-static method, an analytical model is developed to predict the plastic behaviors of the fully clamped metal foam-filled circular tube under the low-velocity impact. Effects of local denting and filled foam strength on the overall bending of the foam-filled tube are considered. Finite element analysis are conducted to study the dynamic response of clamped metal foam-filled circular tube. Good agreement is achieved between the analytical and numerical results. The effect of the filled foam on the dynamic response of the foam-filled tube is discussed. It is demonstrated that the present analytical model is valid to predict the low-velocity of foam-filled circular tubes.
