Solution to a Damped Duffing Equation Using He’s Frequency Approach
The Scientific World Journal, 2022 In this paper, we generalize He’s frequency approach for solving the damped Duffing equation by introducing a time varying amplitude. We also solve this equation by means of the homotopy method and the Lindstedt–Poincaré method.

High Frequency limit of the Helmholtz Equations
Revista Matemática Iberoamericana, 2002 We derive the high frequency limit of the Helmholtz equations in terms of quadratic observables. We prove that it can be written as a stationary Liouville equation with source terms. Our method is based on the Wigner Transform, which is a classical tool for evolution dispersive equations.

Resonant and antiresonant frequencies of multiple cracked bar
Vietnam Journal of Mechanics, 2019 The natural frequencies or related resonant frequencies have been widely used for crack detection in structures by the vibration-based technique. However, antiresonant frequencies, the zeros of frequency response function, are less involved to use for ...
