On Critical Phenomena of a Hysteretic System

  title={On Critical Phenomena of a Hysteretic System},
  author={Zhen Chen and Zhi Qiao Wu and Pei Yu}
In this paper, a nonlinear mechanical system with external forcing is investigated to study the critical phenomena of the system. The system involves a von der Pol type damping and a hysteretic damper representing a restoring force. Numerical simulations are used to show that under an external exciting force, the hysteretic restoring force may not follow the routes described by a conventional form of piecewise function, but exhibit some irregular behavior. We call this unusual situation the… CONTINUE READING
