Modal Analysis of Nonlinear Mechanical Systems

Research output: Chapter in Book/Report/Conference proceeding › Chapter

Abstract

The objective of this chapter is to introduce nonlinear normal modes (NNMs) to structural dynamicists who are not acquainted with them. Specifically, this chapter describes how the concept of modes can be extended to the nonlinear case. It also describes, in simple terms, the fundamental properties of NNMs, including frequency-energy dependence, harmonics, bifurcation, and stability.
