Nonlinear modal analysis of the bar in unilateral contact via analytical weak-solutions to the wave equation

Résumé

Nonlinear modal analysis is commonly performed by detecting families of periodic solutions of nonlinear conservative and autonomous systems. For a unilaterally constrained bar, nonlinear modes were detected using numerical solvers. In the present work, the analytical solution is investigated instead. Results show that infinitely many periodic solutions with the same energy and period might co-exist.
