2. Spectral stochastic finite element method

With regard to the stochastic finite element method in the static framework, the reader may wish to consult [BM 5028] .

In this section, we investigate the frequencies and eigenmodes of a conservative dynamic system, where the mass and stiffness matrices are functions of random parameters. Two perturbation methods are used. The first is the second-order Taylor series expansion. The second is that of Muscolino
