The necessity of reducing fuel consumption and the increasing demands for lightweight vehicles have motivated the use of multi-material combinations. Dissimilar metals have been progressively introduced in different locations to optimize mechanical performance and strength-to-weight ratio. These...

This study focuses on simultaneous vibration suppression and energy harvesting in a broad frequency band. For this purpose, a variant nonlinear energy sink (NES) is developed. The developed variant NES consists of a nonlinear oscillator and an electromagnetic energy harvester. Unlike a true NES,...
