A spectral stochastic finite element formulation with consideration of multi-layer effect and spatial variability of material properties is developed for probabilistic analysis of laminated composite plates. The material properties of each lamina are modeled as a set of random fields and represented

A finite element analysis for the free vibration behaviour of doubly curved shells is presented in which eight-noded curved quadrilateral isoparametric finite elements are used. The first order shear deformation theory for thin and shallow shells is used in the formulation. Results are obtained for
a b s t r a c t New mixed least-squares finite element models are developed for static and free vibration analysis of laminated composite plates. Both models consider the first-order shear deformation theory with generalized displacements and stress resultants as independent variables, using equal a
