Static and free vibration analysis of laminated sandwich shell with double curvature considering the effect of transverse normal strain

Abstract. For the static bending analysis of sandwich spherical shells, higher-order closed-form solutions are provided in current study based on a new hyperbolic shell theory considering effects transverse normal strain. A consists three layers wherein top and bottom (face sheets) made up hard material middle layer (core) is soft material. The governing equations associated boundary conditions produced by employing principle virtual work. Semi-analytical for problem Navier technique simply supported shell. present results compared with that have already been published order to confirm accuracy efficacy theory.
