The paper proposes the evaluation of the effect of stochastic space-dependent temperature and moisture variations on the buckling response of laminated composite plates, considering both Gaussian and non-Gaussian random fields. Discussions and conclusions are brought justifying the importance of incorporating environmental uncertainties in the analysis and design of aerospace composite structures.
