Dynamic response of multilayered composite conical shells subjected to lateral impulsive pressure loads

Dynamic response of multilayered composite conical shells under lateral impulsive pressure loads is studied.Classical shell theory (CST) was utilized in the shell’s equilibrium equations and strain-displacement relations were based on Love’s first approximation theory. Equilibrium equations for free and forced vibration problems of the shellwere solved using Galerkin method. The pressure pulse load is applied on a quadrilateral area over the internal/external surface of the conical shell at arbitrary point. The accuracy of the analysis has been examined by comparing the results with those obtained by finite element method using ABAQUS commercial software and good agreement is achieved
