This paper aims to investigate the interlaminar stresses of laminated composite doubly-curved shells on a rectangular planform subjected to concentrated force using various equivalent single layer shell theories recovered via generalized mathematical formulation. A generalized higher-order shell theory presented herein uses various polynomial and nonpolynomial type shear strain functions available in the literature to account for the effect of transverse shear deformation. Closed-formed analytical solutions are obtained using the Navier’s solution technique. Interlaminar stresses are recovered based on the direct integration of three-dimensional equilibrium equations of the theory of elasticity to capture the effect of stress concentration due to concentrated forces. The numerical results for transverse deflection are compared with previously published results wherever possible. Through-the-thickness distributions of in-plane normal and transverse shear stresses are presented to clearly understand the stress concentration effects due to concentrated force.
