论文摘要
堵塞的软盘在准静脉剪切下表现出颗粒重排的雪崩。我们使用最陡峭的下降遵循雪崩，将它们分解为单个局部重排。我们通过机器学习的数量（柔软度）来表征每个粒子的局部结构环境，该数量与重排高度相关，并分析柔软度，重排和应变之间的相互作用。我们的发现构成了包括局部结构的增强弹性塑料模型的基础。
Jammed soft disks exhibit avalanches of particle rearrangements under quasistatic shear. We follow the avalanches using steepest descent to decompose them into individual localized rearrangements. We characterize the local structural environment of each particle by a machine-learned quantity, softness, designed to be highly correlated with rearrangements, and analyze the interplay between softness, rearrangements and strain. Our findings form the foundation of an augmented elastoplastic model that includes local structure.
