Polyurethane Foam-Filled Energy Absorption Connectors Under Impact
Two types of polyurethane (PU) foam-filled energy absorption connectors were proposed, aiming to improve the energy absorption performances of aluminum foam-filled connectors. The multiple pleated (MP) plates and asymmetric pleated (AP) plates were employed for the PU foam-filled energy absorption connectors, which could trigger more plastic hinges and achieve higher energy absorption. Drop-weight impact tests and Finite Element simulations on the PU foam-filled energy absorption connectors were carried out to obtain their deformation modes and energy absorption performances. In addition, an analytical model including strain rate effects of both steel and PU foam was proposed, and it could be employed as a simple alternative to quickly obtain the force–displacement relation of the connector. The accuracy of the developed analytical model was also validated against the experimental and numerical results.
