Journal ArticleDOI
Application of Neural Networks for Detection of Changes in Nonlinear Systems
TL;DR: In this article, a nonparametric structural damage detection methodology based on nonlinear system identification approaches is presented for the health monitoring of structure-unknown systems, which relies on the use of vibration measurements from a healthy system to train a neural network for identification purposes.
Journal ArticleDOI
Random Excitation of a System With Bilinear Hysteresis
TL;DR: In this article, an analysis of the response of a system with bilinear hysteresis to random excitation is made, and it is shown that for moderately large inputs, the additional damping created by the biliniear hystresis decreases the mean squared deflection compared with that for a linear system with the same viscous damping.
Journal ArticleDOI
Identification of Nonlinear Dynamic Systems Using Neural Networks
TL;DR: In this article, the authors explore the potential of using parallel distributed processing methodologies (artificial neural networks) to identify the internal forces of structure unknown non linear dynamic systems, and explore the use of neural networks to predict the internal dynamics of non-linear dynamic systems.
