Experimental investigation,energy balance and finite element method were developed in this paper to study the dynamic response of metallic sandwich panel subjected to blast loading.First,an experimental set-up which could investigate the dynamic response of sandwich panel under blast loading was presented.Then,the deflection equation of sandwich panel was obtained which was based on an energy balance and assumed deflection field.Finally,finite elements simulations were undertaken using the LS-DYNA software,such as deformation processes of the sandwich panel.Both models were validated by comparing their predictions with the test results available in the literature.Parametric studies were then carried out to assess various factors that are influential in charactering dynamic behavior of sandwich panels subjected to blast loads.The result shows that,for the purposes of improving the impact resistance of sandwich panel can be realized by the method of increasing density of the foam core,thickness of face-sheets and foam core.
