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.
Journal ArticleDOI
Nonlinear normal modes, Part II: Toward a practical computation using numerical continuation techniques
TL;DR: In this paper, a nonlinear normal mode (NNM) computation is shown to be possible with limited implementation effort, which paves the way to a practical method for determining the NNMs of nonlinear mechanical systems.
Journal ArticleDOI
Physical interpretation of the proper orthogonal modes using the singular value decomposition
TL;DR: In this paper, the authors provide insights into the physical interpretation of the proper orthogonal modes using the singular value decomposition (SVD) in the field of structural dynamics.
Journal ArticleDOI
Structural damage diagnosis under varying environmental conditions—part II: local PCA for non-linear cases
TL;DR: A local PCA-based damage detection method is applied for the structural health monitoring of a real bridge using vibration data measured in situ over a one-year period.
Journal ArticleDOI
Output-only modal analysis using blind source separation techniques
TL;DR: The present study carries out output-only modal analysis using two blind source separation techniques, namely independent component analysis and second-order blind identification using the concept of virtual source.
