Abstract
This study is concerned with free and forced undamped purely nonlinear oscillators. First, the exact closed-form solution for free vibrations given in terms of the Ateb function is discussed. An insight is provided with respect to the period of vibrations and the harmonic content of the response. Then, forced purely nonlinear oscillators with an Ateb-type external excitation are considered. The exact solution for the forced response is obtained, the amplitude-frequency equation derived and frequency-response curves investigated. It is also shown how one can adjust the system parameters to cause a constant frequency/period of the forced response.
