Abstract (EN): This article describes a finite element based formulation for the statistical analysis of the response of stochastic structural composite systems whose materials and loads are described by random fields. A first-order technique is used to obtain the second order statistics for the structural response considering means and variances of the displacement and stress fields of plate or shell composite structures with several boundary conditions. Dominant effects on the stochastic characteristics are studied comparing the influence of different random parameters.
