About this document
Stability Analysis of Nonlinear Bars by Nidish Narayanaa is a document available to read on EtoBox.
This paper develops two new approaches for assessing the stability of nonlinear wave-based solutions for jointed elastic bars: 1) A strained parameter approach that constructs analytical stability boundaries by perturbing a stiffness parameter and using wave-based methods. This accurately determines stability for a system of two bars connected by a nonlinear joint. 2) A perturbation eigenproblem residue (PER) approach that locates stability changes by examining the sign of the residue of the perturbed sys
