Experimental, numerical, and analytical studies on polyurethane foam-filled energy absorption connectors under quasi-static loading
Abstract This paper proposes a novel polyurethane foam-filled energy absorption connector with advanced geometry to dissipate energy. Quasi-static loading tests of these connectors were first conducted to evaluate failure mechanisms and energy absorption performances. Numerical and analytical models which exhibited results consistent with those of the experiment were developed to predict and conduct an in-depth study of the energy absorption characteristics. The results revealed that most energy absorption parameters could be enhanced by filling polyurethane foam, increasing the armed plate thickness, and decreasing the height from the top of the armed plate to the intersecting point of the two arms. The findings from this work help understand the failure mechanism and energy absorption behaviour of the proposed connectors, and they will promote potential applications of these connectors in terms of dissipating blast or impact energy.
Highlights The polyurethane foam-filled connectors were tested under quasi-static loading. The energy absorption performance of the connector could be improved by filling polyurethane foam. Numerical model was developed to simulate the response of the connector. Analytical model was developed to predict the absorbed energy–displacement response.
