Subharmonics and Ultraharmonics in the Forced Oscillations of Weakly Nonlinear Systems
(American Journal of Physics, 1976-06)
The characteristics of subharmonic and ultraharmonic modes appearing in the forced, steady?state oscillations of weakly nonlinear systems are considered from the physical, rather than mathematical, viewpoint. A simple ...
Viscous Effects on Small-Amplitude Surface Waves
(The Physics of Fluids, 1976-02)
The transient behavior of small?amplitude standing waves on the plane surface of an infinitely deep viscous liquid is investigated. An integro?differential equation of motion for the free surface is derived and solved ...
