Damping of vibrations of a rod by dissipation due to diffusion

Year: 2024

Type: article

Abstract: Understanding the interaction of vibrations with diffusion, e.g. of carbon in fcc lattice , is still of practical relevance. An analytical framework is offered based on the mechanics and thermodynamics, where the evaluated total dissipation by diffusion allows calculation of damping of a vibrating rod from the Gibbs energy balance. Finally, a simple relation is found relating the diffusion coefficient , geometry and elastic properties of the rod with its damping coefficient . This method could be utilized for measurement of the diffusion coefficient .
