Acoustically-induced slip in sheared granular layers: application to dynamic earthquake triggering [PDF]
, 2015 A fundamental mystery in earthquake physics is ``how can an earthquake be triggered by distant seismic sources?'' Here, we use discrete element method simulations of a granular layer, during stick-slip, that is subject to transient vibrational excitation

On the influence of external stochastic excitation on linear oscillators with subcritical self-excitation applied to brake squeal [PDF]
, 2019 A characteristic of linear systems with self-excitation is the occurrence of non-normal modes. Because of this non-normality, there may be a significant growth in the vibration amplitude at the beginning of the transient process even in the case of ...
