Effect of Slip Surface’s Continuity on Slope Dynamic Stability Based on Infinite Slope Model
Mathematics, 2019 The slip surface is an important control structure surface existing in the landslide. It not only directly affects the stability of the slope through the strength, but also affects the stress field by affecting the propagation of the stress wave.

Oscillatory wave fronts in chains of coupled nonlinear oscillators [PDF]
, 2003 Wave front pinning and propagation in damped chains of coupled oscillators are studied. There are two important thresholds for an applied constant stress $F$: for $|F| F_{cs}$ (static Peierls stress) there are only stable moving wave fronts.
