Nonlinear 2DOF van der Pol vibrations: El-Dib’s optimized frequency formula via the two-time-domains method

This paper presents a systematic decoupling framework for strongly coupled two-degree-of-freedom (2-DOF) nonlinear vibration systems. Here, the coupling is classified as strong rather than weak because the cross-mode interaction terms in the governing equations (e.g., the x 2 y-,...
