An Approximate Solution for a Nonlinear Duffing – Harmonic Oscillator

Van Hieu – Dang · Asian Research Journal of Mathematics · 2019

The equivalent linearization method introduced by Caughey is a powerful tool for analyzing random oscillations. The method is also easy to apply for deterministic oscillations. However, with strong nonlinear systems, the error of this method is usually quite large and even not ac...

Nonlinear Vibration of Microbeams under Magnetic Field Using the Modified Couple Stress Theory

Van Hieu – Dang, Quang Duy – Le & Kim Thoa – Nguyen · Asian Research Journal of Mathematics · 2019

In this work, nonlinear vibration of microbeams under magnetic field is studied. The equation governing motion of microbeam resting on a linear elastic layer and under magnetic field is derived by using the modified couple stress theory and Hamilton’s principle. Amplitude–frequen...
