论文摘要
我们研究了引入的弹性塑料模型的平均场极限，以描述Athermally和Quasi剪切的无定形固体的屈服过渡。我们专注于样本到样本的波动，我们通过分析表征，并详细研究了与Athermer驱动的随机场ISING模型的类比。我们强调，屈服过渡时的随机场是一种新兴障碍，我们研究了决定其强度的各种因素。
We study the mean-field limit of an elasto-plastic model introduced to describe the yielding transition of athermally and quasi-statically sheared amorphous solids. We focus on the sample-to-sample fluctuations, which we characterize analytically, and investigate in detail the analogy with the athermally driven random-field Ising model. We stress that the random field at the yielding transition is an emerging disorder and we investigate the various factors that determine its strength.
