Analytical and Experimental Studies of the Quantification and Propagation of Uncertainties in Nonlinear System Modeling and Simulation

Abstract

The research objectives of this project were focused on developing methods and procedures suitable for use with dynamic response measurements from flexible structural components and assemblages that may incorporate elements undergoing significant multi-dimensional nonlinear deformations. By using a powerful model-free approach to obtain computationally efficient reduced-order models, a general framework was developed for the probabilistic representation and propagation of measured uncertainties in the stochastic nonlinear test articles, their related nonparametric nonlinear model, and the corresponding probabilistic time-history response of the physical system.
