Abstract
In this work we investigate discrete structures with local hysteretic effects regarding energy flow and wave propagation. The dynamic behavior is pointed out using an oscillator chain with local dissipation source leading to non-proportional damping. Both, a linear viscous damping element and a nonlinear Coulomb sliding element are considered in this study. For steady state solutions, in the case of linear damping, complex modal analysis is applied. The solution of the nonlinear system is approximated utilizing the Harmonic Balance method. We show how the intensity of local dampers influences the formation of traveling waves and thus affects the dynamic design process.
