A Modified Computational Scheme for the Stochastic Perturbation Finite Element Method

Abstract A modified computational scheme of the stochastic perturbation finite element method (SPFEM) is developed for structures with low-level uncertainties. The proposed scheme can provide second-order estimates of the mean and variance without differentiating the system matrices with respect to...
