近距空爆下复合抗爆舱壁变形破坏模式试验研究
Experiments analysis of air exploded impacts on blast resistant bulkhead
The effect of blast-loaded on the response of fully clamped circular composite resistant structure in warship,comprising mild steel plates and GFRP cores of radius 500 mm are repoted. The procedure consists of creating a blast load using explosive mounted onto the upper mild steel plates. The stand-off distance is varied, from 167 to 334 mm, using uniform TNT mounted . The plates responses range from large inelastic bucket deformation to complete tearing at the boundary . Different loading regimes are observed, depending on the stand-off distance between the explosive charge and the plates, and are classifed according to the plates response. Appropriate analyses are introduced to account for the effect of stand-off distance on composite resistant structure deformation.
