Document Type: Proceeding Paper

Part of: Structural Safety and Reliability

Abstract:

Methods are developed for estimating the probability of oscillations on the lower and upper stable branches of the input-output amplitude relationship for a Duffing oscillator subject to a narrow band stationary Gaussian excitation. The analysis is based on the crossing theory of differentiable processes and diffusion models. Proposed estimates are evaluated by simulation.
