How Surface Governs Vibration-Induced Degradation of Glass Structure: A View from Molecular Dynamics

However, mechanical fields encountered during services will lead to the performance degradation or even failure. These remain not fully understood due to the limitations of experimental techniques and the disordered structures of glass and their complex responses.

In this study, characteristics of structural responses and evolution mechanisms under the vibration field are systematically analyzed through MD simulations. Fourier transform of the RMSD, as well as the reduced pair distribution function, G(r), have been applied to analyze the glass structure. In addition, the vibration field can induce significant alterations to the structural order, especially for the surface models.
