Contradictory scaling behavior in experiments testing the principle of universality may be due to external oscillations.Thus, the effect of damped oscillatory external forces on slip avalanches in slowly deformed solids is simulated using a mean-field model.Akin to luau thank you cards a resonance effect, oscillatory driving forces change the dynamics of avalanches with durations close to the oscillation period.This problem can be avoided by tuning mechanical resonance frequencies away from the range of the inverse avalanche durations.

The results provide critical guidance il barone wine for experimental tests for universality and a quantitative understanding of avalanche dynamics under a wide range of driving conditions.
