Stochastic dynamics of nonlinear systems driven by non-normal delta-correlated processes

The dynamic behavior of nonlinear systems driven by parametric normal delta-correlated processes is studied. A modified version of Ito's stochastic differential calculus that contains the Wong-zakai ot Stratonovich correction term is used to characterize the systems'response under stochastic excitations. The results of this approach are found to be consistent with experimental data obtained by means of a Monte Carlo simulation.
