热循环作用下颗粒堆的蠕变运动
Creep motion of a granular pile induced by thermal cycling
摘要：
我们报告了一个时间分辨的动态研究与缓慢压实的颗粒列提交热循环。柱高表现出复杂的行为：对于大幅度的温度循环，颗粒柱连续沉降，在每个循环中经历小的沉降;相比之下，对于足够小的幅度，柱表现出不连续和间歇性的活动：连续的塌陷被持续时间呈指数分布的静止期分开。然后，我们讨论了潜在的机制，这将占在有限振幅的压实和过渡。
英文摘要：
We report a time-resolved study of the dynamics associated with the slow compaction of a granular column submitted to thermal cycles. The column height displays a complex behavior: for a large amplitude of the temperature cycles, the granular column settles continuously, experiencing a small settling at each cycle; By contrast, for small-enough amplitude, the column exhibits a discontinuous and intermittent activity: successive collapses are separated by quiescent periods whose duration is exponentially distributed. We then discuss potential mechanisms which would account for both the compaction and the transition at finite amplitude.
