Freeplay Nonlinearity

Freeplay Nonlinearity is a mechanical nonlinearity in aeroelastic systems characterized by a deadband or backlash in control surface hinge moments, where the control surface exhibits zero restoring force over a finite range of displacement, distinguishing it from continuous stiffness or hysteresis-type nonlinearities.
