Journal ArticleDOI
Past, present and future of nonlinear system identification in structural dynamics
TL;DR: In this article, a review of the past and recent developments in system identification of nonlinear dynamical structures is presented, highlighting their assets and limitations and identifying future directions in this research area.
Journal ArticleDOI
The Method of Proper Orthogonal Decomposition for Dynamical Characterization and Order Reduction of Mechanical Systems: An Overview
Gaëtan Kerschen,Gaëtan Kerschen,Gaëtan Kerschen,Jean Claude Golinval,Alexander F. Vakakis,Alexander F. Vakakis,Lawrence A. Bergman +6 more
TL;DR: In this article, a different approach is adopted, and proper orthogonal decomposition is considered, and modes extracted from the decomposition may serve two purposes, namely order reduction by projecting high-dimensional data into a lower-dimensional space and feature extraction by revealing relevant but unexpected structure hidden in the data.
Journal ArticleDOI
Nonlinear normal modes, Part I: A useful framework for the structural dynamicist
TL;DR: The concept of nonlinear normal modes (NNMs) is discussed in the present paper and its companion, Part II as mentioned in this paper, and numerical methods for the continuation of periodic solutions pave the way for an effective and practical computation of NNMs, and timefrequency analysis is particularly suitable for the analysis of the resulting dynamics.
Book
Nonlinear Targeted Energy Transfer in Mechanical and Structural Systems
Alexander F. Vakakis,Oleg Gendelman,Lawrence A. Bergman,D. M. McFarland,Gaëtan Kerschen,Young S. Lee +5 more
TL;DR: In this article, the authors proposed a method for targeted energy transfer in discrete linear Oscillators with single-DOF nonlinear energy sinks, and demonstrated the effect of TRCs and TET in the Damped and Forced System.
Journal ArticleDOI
Structural damage diagnosis under varying environmental conditions—Part I: A linear analysis
TL;DR: In this paper, a damage detection method based on principal component analysis (PCA) applied to vibration features identified during the monitoring of the structure is proposed for structural health monitoring under varying environmental and operational conditions.
