✦ Synopsis

The purpose of the paper is to present a closure technique based on the representation of the non-linear system response process to a random excitation by a polynomial function of Gaussian process. It is shown that for the unimodal and bimodal situations of the Duffing oscillator, the proposed technique can give good approximate response moments as well as the probability density function and power spectral density of the system response.

Gaussian processes that are multifractional are studied in this paper. By multifractional processes we mean that they behave locally like a fractional Brownian motion, but the fractional index is no more a constant: it is a function. We introduce estimators of this multifractional function based on
