摘要

Plastic flow of single crystal micropillars proceeds through a sequence of intermittent burst slips.The burst time durations are investigated based on an extended theoretical model which incorporates the observed power-law distribution of burst sizes in compression experiments of micropillars.The results show that the burst time durations exhibit a powerlaw behavior with an exponential cutoff,suggesting the same scaling behaviors as the burst sizes.In addition,the predicted scaling exponent is found to converge to a value of ～1.6.It is demonstrated that our results are consistent with the experimental data.
