An analytical solution to the problem of deformation of a finite-dimensional general cross-ply thick doubly-curved panel with negative Gaussian curvature and of rectangular plan-form, modeled using a higher order shear deformation theory (HSDT), is presented. A solution methodology, based on a boundary-discontinuous generalized double Fourier series approach is used to solve a system of five highly coupled linear partial differential equations, generated by the HSDT-based laminated shell analysis, with the SS2-type simply supported boundary condition prescribed on two opposite edges, while the remaining two edges are subjected to the SS3-type constraint. Hitherto unavailable important numerical results presented include sensitivity of the predicted response quantities of interest to shell geometry (negative or positive Gaussian curvature), surface-parallel boundary constraints, lamination and thickness effects, as well as their interactions.
