Interaction of the fundamental frequencies of a torsional cantilever nanobeam and spring mass system single degree of freedom (SDOF) under axial load, including buckling

Abstract

Article Highlights 1. Coupled systems exhibit local natural frequencies which contribute to a unique universal natural frequency for the system. 2. The interaction of the local natural frequencies causes an amplification or attenuation in the displacement and acceleration. 3. By manipulating the universal natural frequencies of a nanobeam tool with tip-mass, we can control contact forces.
