On the interaction of exponential non-viscous damping with symmetric nonlinearities [PDF]
, 2008 This paper studies the interaction between non-viscous damping and nonlinearities for nonlinear oscillators with reflection symmetry. The non-viscous damping function is an exponential damping model which adds a decaying memory property to the damping ...
