Abstract The nonlinear free vibration behaviour of laminated composite spherical shell panel under the elevated hygrothermal environment is investigated in this article. The composite material properties are considered to be the function of temperature and moisture concentration and the effective properties are evaluated using the micromechanics approach. The laminated shell panel model is developed mathematically using Green–Lagrange nonlinear kinematics in the framework of the higher-order shear deformation theory. The model is discretised using suitable finite element steps and solved numerically through a direct iterative method. The significance of the present nonlinear model is highlighted by solving the wide variety of numerical examples.
