The dynamic behavior of a 2DOF system consisting of a primary structure and a hysteretic vibration
attachment is investigated. With respect to viscoelastic tuned mass damper, which works in internal resonance
condition (1:1), the systems with the nonlinear attachment can exhibit different internal resonance conditions
(n:1), with n>1. Such these conditions be met, hysteresis produces bifurcations and superabundant nonlinear
modes which are shown to be very effective in reducing the response of the primary structure
