Aluminum Foam-Filled Energy Absorption Connectors Under Impact
In this chapter, two types of aluminum foam-filled energy absorption connectors were proposed for resisting impact and blast loads. The drop-weight impact tests were conducted to obtain the crushing behaviors of the proposed energy absorption connectors, and their deformation modes were also obtained. Moreover, the effects of loading rate, aluminum foam filler, geometric parameters of curved plates/pleated plates on the energy absorption performances of the connectors were quantitatively evaluated. The aluminum foam filler was found to significantly improve the energy absorption performance. The numerical studies on the tested connectors were conducted by employing the explicit code in LS-DYNA. The analytical models considering the strain rate effect of mild steel were developed to predict the force–displacement responses of the aluminum foam-filled energy absorption connectors under impact load. Finally, a design method was proposed for conducting blast resistant design of the structures utilizing the energy absorption connectors as additional energy absorbers.
