Abstract
The basis of a new boundary element method adapted to wide frequency range applications is proposed in this paper. The formulation employs the frequency domain dynamic fundamental solutions of the problems. Random geometrical parameters are introduced in the integral equations. These equations are then modified to exhibit the products of the different kinematic variables. The expectations of the new equations with respect to the latter random variables are considered, and the new variables of the formulation are the different stochastic moments force-displacement variables. This formulation is applied to different structures, such as beams, rods and assembled one-dimensional systems.
