Peak response of non-linear oscillators under stationary white noise

Description

The use of the Advanced Censored Closure (ACC) technique, recently proposed by the authors for
predicting the peak response of linear structures vibrating under random processes, is extended to
the case of non-linear oscillators driven by stationary white noise. The proposed approach requires
the knowledge of mean upcrossing rate and spectral bandwidth of the response process, which in
this paper are estimated through the Stochastic Averaging method. Numerical applications to
oscillators with non-linear stiffness and damping are included, and the results are compared with
those given by Monte Carlo Simulation and by other approximate formulations available in the literature.
