   Abstract:
   The approximate fundamental response of a driven mechanical oscillator with a quadratic stiffness characteristic is studied by using the method of harmonic balance. The accuracy of the periodic solutions based on first approximation theory, and their stability, are compared with exact results obtained from direct time integration.
