This work deals with the stochastic free vibration of laminated composite plates subjected to a thermal loading with general boundary conditions by taking into account the randomness in lamina material properties and thermal expansion coefficients. The system equations have been derived based on higher order shear deformation theory incorporating rotary inertia effects. A C 0 finite element method is used for treating the random eigenvalue problem. A mean centered first-order perturbation technique is adopted to examine the stochastic characteristics of thermal free vibration response. The results have been compared with those available in the literature and independent Monte Carlo simulation.
