What is Large-Amplitude Vibrations of Beams about?

This document summarizes a study that re-investigated the large-amplitude free vibrations of beams using finite element analysis. The study iteratively solved dynamic finite element equations to obtain converged mode shapes that exactly satisfied axial and out-of-plane equations, without assuming harmonic oscillations. This allowed reduction of the equations to a scalar equation relating normalized displacement and time. Numerical integration of this equation provided accurate predictions of nonlinear natur
