3. Stochastic finite element methods

The preceding paragraphs have clarified the position of the problem, which is summarized as follows:

Given {X } a vector of random variables of dimension nva, a rigidity matrix K ({X }) and a vector of actions F ({X }), find the stochastic properties of the vector q ({X }) such that K ({X }) q ({X }) = F ({X }).

This section examines solutions using the perturbation method and polynomial chaos.
