摘要: Abstract A tube-core sandwich panel was designed to serve as anti-blast of blast resistant walls. Steel tubes are non-expensive and strong for walls, can be easily connected with face sheets through welding. Static three-point bending experiments, close-in explosion experiments contact were performed explore its ability. The tough interface shear-resistant endow the high rigidity. In explosion, front mitigates shock wave corrugations corrugated plastic deformation is rigid enough resist wave. attenuates tube-crushing skin-tearing. Appropriate thicknesses tube wall promote energy absorption. indicate that spaced better choice explosions while has advantages under explosions.
