Abstract:We perform a detailed study of the dynamics of a nonlinear, one-dimensional oscillator driven by a periodic force under hysteretic damping, whose linear version was originally proposed and analyzed by Bishop in [1]. We first add a small quadratic stiffness term in the constitutive equation and construct the periodic solution of the problem by a systematic perturbation method, neglecting transient terms as $t\rightarrow \infty$. We then repeat the analysis replacing the quadratic by a cubic term, which does not… Show more
“…In [15], a detailed study was performed on the dynamics of a hysteretic damping model introduced by Reid [16], for a linear as well as nonlinear oscillator driven by a T -periodic sinusoidal force. Reid's model was shown to be free from numerical limitations suffered by a hysteretic damping model proposed earlier by Bishop [17], since Reid's oscillator is expressed by a differential equation whose real and imaginary parts have the same solutions.…”

“…Thus, numerical errors occurring during the integration of Reid's model are efficiently controlled, and it is shown to possess T -periodic solutions, which are true attractors. Moreover, in the weakly dissipative case, it exhibits the coexistence of periodic attractors of period nT, n = 2, 3, ..., with very interesting basins of attraction in the space of initial conditions [15]. Reid's model [16] describes the evolution of a one degree-of-freedom (dof) oscillator with mass M under periodic forcing of amplitude f , satisfying the differential equation:…”

“…Model I is a nonlinear extension of the well-known quasi-linear Reid's model [16,15]. In Section 2, we numerically integrate its equations of motion and study the occurrence of supratransmission, analyzing the effect of the system's parameters on the corresponding critical amplitudes.…”
Energy transport in 1-dimensional oscillator arrays has been extensively studied to date in the conservative case, as well as under weak viscous damping. When driven at one end by a sinusoidal force, such arrays are known to exhibit the phenomenon of supratransmission, i.e. a sudden energy surge above a critical driving amplitude. In this paper, we study 1-dimensional oscillator chains in the presence of hysteretic damping, and include nonlinear stiffness forces that are important for many materials at high energies. We first employ Reid's model of local hysteretic damping, and then study a new model of nearest neighbor dependent hysteretic damping to compare their supratransmission and wave packet spreading properties in a deterministic as well as stochastic setting. The results have important quantitative differences, which should be helpful when comparing the merits of the two models in specific engineering applications.
