A novel efficient method to evaluate the dynamic response of laminated plates subjected to underwater shock

摘要: Abstract UNDerwater EXplosions (UNDEX) can cause severe damage to submarines, ships and offshore infrastructures as well deep-sea fuel transfer installations, most of which are made laminated plates shells. A novel method involving an analytical technique connected with the elastic dynamic response subjected UNDEX is proposed here. It based on state space method, a numerical inversion Laplace transform fluid–structure interaction (FSI) theory formulated by Taylor. Two algorithms for numerically inverting also proposed, these computations apparently more efficient than be found in related literature. The present validated undertaking comparison semi-analytical experiment results derived from literature written subject, finite element analysis (FEA). cooperation deemed strong accurate FEA. influence FSI investigated detail case study using both stiff flexible plate. show that significantly influences reaction solution may assist promoting understanding acoustic responses submerged structures plates, might used benchmark further research.
