Steel–concrete–steel (SCS) sandwich panels are an effective means for protecting personnel and infrastructure
facilities from the effects of external blast and high-speed vehicle impact. In conventional
SCS construction, the external steel plates are connected to the concrete infill by welded shear stud connectors.
This paper describes a programme of research in which the non-composite SCS panels with axially
restrained connections were studied experimentally and numerically. High fidelity finite element
models for axially restrained steel–concrete–steel panels subjected to impact loading conditions were
developed using LS-DYNA. The simulation results were validated against the dynamic testing experimental
results. The numerical models were able to predict the initial flexural response of the panels followed
by the tensile membrane resistance at large deformation. It was found that the strain rate effects of the
materials and the concrete material model could have significant effect on the numerically predicted flexural
strength and tensile membrane resistance of the panels.
