Final Solution of Duffing Equation of Mixed Parity

The Duffing-type equation is useful and necessary to examine the uniqueness of angular frequency from the equation of motion and its energy relations, using the harmonic balance with lower-order harmonics. The frequency-amplitude relation obtained for the Duffing-type equation will also be useful in...

Description
Summary:The Duffing-type equation is useful and necessary to examine the uniqueness of angular frequency from the equation of motion and its energy relations, using the harmonic balance with lower-order harmonics. The frequency-amplitude relation obtained for the Duffing-type equation will also be useful in understanding the nonlinear free-vibration characteristics of composite structures.
