Abstract: The transient behaviour of laminated composite spherical shell cap is investigated using the finite element method . An eight node degenerated isoparametric shell element is considered with five degrees of freedom at each node. The governing equations of forced vibration are solved using the Newmark’s direct integration method. Results are presented for dynamic response of deflection and stresses of orthotropic and laminated spherical shell caps subjected to suddenly applied uniform normal pressure.
