摘要：
Steel tubes process excellent performance of energy absorption. Sandwich panels have advantages in strength and rigidity. The tube-core sandwich panels used for blast resistant were studied in this paper. Contact blast experiments with 1 kg TNT were carried out to test the five-tube-core sandwich panel, the four-tube-core sandwich panel, and the three-tube-core sandwich panel. For each panel, the deformation and failure subjected to contact blast loading were investigated. The process of deformation and failure were researched by theoretical analysis and numerical simulation. Researches show that the tube-core sandwich panels consume energy mainly by local compression deformation. To reduce the deformation and improve the contact blast resistance of the sandwich panels, it is effective to increase the number of tubes or enlarge the thickness of face sheets and tube walls. © 2017, Editorial Office of Journal of Vibration and Shock.
