Steel-PU Foam-Steel–Concrete-Steel Panel Under Impact
A new steel-polyurethane foam-steel–concrete-steel (SPUFSCS) panel, which consists of “soft” and “stiff” layers, was proposed, and its impact resistant performance was experimentally, numerically and analytically studied. Experimental studies on SPUFSCS panels under impact loading were first conducted by employing an instrumented drop-weight impact test system to reveal their failure modes, impact force and displacement responses. The Finite Element (FE) models of the tested SPUFSCS panels under impact loading were established and validated against the experimental results. Numerical results indicated that the impact energy dissipated by the “soft” layer is higher than that of “stiff” layer, which demonstrated the benefits of employing “soft” layer on improving the impact resistance of the traditional SCS panel. In addition, an analytical model was also presented for predicting the displacement response of the SPUFSCS panel under impact loading.
