Journal ArticleDOI
A path-following technique via an asymptotic-numerical method
TL;DR: In this article, a path-following technique is presented for the numerical solution of a class of elastic structural problems, which is based on applying a perturbation technique in a stepwise manner.
Journal ArticleDOI
A high order purely frequency-based harmonic balance formulation for continuation of periodic solutions
Bruno Cochelin,Christophe Vergez +1 more
TL;DR: In this article, an alternative approach that can be applied to a very large class of dynamical systems (autonomous or forced) with smooth equations is presented. But the main idea is to systematically recast the dynamical system in quadratic polynomial form before applying the harmonic balance method.
Journal ArticleDOI
Asymptotic-numerical methods and pade approximants for non-linear elastic structures
TL;DR: In this article, the non-linear branches are sought in the form of asymptotic expansions, and they are determined by solving numerically (FEM) several linear problems with a single stiffness matrix.
Journal ArticleDOI
Numerical computation of nonlinear normal modes in mechanical engineering
TL;DR: In this article, a review of the recent advances in computational methods for nonlinear normal modes (NNMs) is presented, and different algorithms for the computation of undamped and damped NNMs are discussed.
Journal ArticleDOI
Experimental study of targeted energy transfer from an acoustic system to a nonlinear membrane absorber
TL;DR: In this paper, an experimental set-up has been developed using the air inside a tube as the acoustic linear system, a thin circular visco-elastic membrane as an essentially cubic oscillator and the air outside a box as a weak coupling between those two elements.
