چکیده مقاله
In this article, stochastic finite element and spectral finite element methods are combined as a new hybridized numerical method for uncertainty quantification A popular version of stochastic finite element method is used for the combination In the other hand, spectral finite element method is a numerical method employing special orthogonal polynomials e g , Lobatto and quadrature schemes e g , Gauss Lobatto Legendre , leading to desirable accuracy, and much less domain discretization with excellent convergence The proposed method of this study is a hybrid method utilizing efficiencies of both methods for analysis of stochastically linear elastostatic problems Additionally, spectral finite element is utilized fornumerical solution of Fredholm integral equation followed by the proposed numerical method, one which increases the efficiencies Numerical examples demonstrate abilities of the proposed method
