论文摘要
对弹性界面的大量研究已经对界面用恒定力推动的系统进行了大量研究。我们研究了在蠕变区域内正弦驱动下界面的平均速度，考虑了磁滞回路期间的磁性域壁等短距离弹性系统以及诸如裂缝之类的长范围系统。我们获得了具有近似幂律行为的蠕变速度的修改版本，并获得了短距离系统的材料依赖指数，并为远程弹性提供了更简单的行为。我们讨论该模型是否可以应用于疲劳性骨折，还是需要额外的物理学。
Plenty of research on elastic interfaces has been done on systems where the interface is pushed with a constant force. We studied the average velocity of an interface under a sinusoidal driving in the creep region, considering both short-range elastic systems, such as magnetic domain walls during a hysteresis loop, and long ranged systems such as fractures. We obtained a modified version of the creep velocity with approximate power-law behaviour and a material dependent exponent for short ranged systems and simpler behaviour for long-range elasticity. We discuss whether the model can be applied to fatigue fractures, or if extra physics is needed.
