TY - JOUR TI - Local fractional Duffing equation: Its periodic property and its application to energy harvesting AU - Yang Yong-Ju AU - Han Guo-Li AU - Hua Liu-Qing JN - Thermal Science PY - 2024 VL - 28 IS - 3 SP - 2135 EP - 2142 PT - Article AB - A local fractional modification of the Duffing equation is considered, and the homotopy perturbation method is employed to reveal its frequency-amplitude relationship, which is of paramount importance in the optimal design of the energy harvesting devices and chatter detection. Effects of the initial conditions on the periodic property is also discussed.
