Su Altı Patlama Yüküne Maruz Sandviç Kompozit Panellerin Nümerik Analizi

Underwater explosions are tremendously hazardous for floating structures and human life inside. When compared to an air blast, underwater blast is more effective due the effect of fluid domain. Therefore, design marine with high strength a difficult subject as well important. With rapid progression material technology, composite materials widely preferred over metals in fields defense industries low density, elasticity their nature. In this study, sandwich panel soft-core was modelled using finite element method, dynamic behavior subjected load investigated. validation study model firstly, responses carbon epoxy plate structure explosion were confirmed results available literature. part, ALE (Arbitrary Lagrangian-Eulerian) Load_SSA (Sub Sea Analysis) methods used simulate response very good agreement observed by method. Then, panels (foam) investigated element-based Finally, maximum deflection loads examined parametric studies. Increasing core layer thickness caused decrease deflections increase post-explosion oscillation frequency under same conditions.
