论文摘要
在这封信中，我们开发了一个框架，通过中尺度和微观模型的耦合来研究无形无定形固体的机械响应。使用来自密集无序颗粒系统的模拟的粗粒量的测量，我们提出了一种连贯的弹性塑料模型方法，用于变形和屈服应力材料的流动。对于给定的一组参数，该模型允许在应用剪切率和蠕变协议下始终如一地匹配驱动无序系统的暂时性和稳态特征。
In this letter, we develop a framework to study the mechanical response of athermal amorphous solids via a coupling of mesoscale and microscopic models. Using measurements of coarse grained quantities from simulations of dense disordered particulate systems, we present a coherent elasto-plastic model approach for deformation and flow of yield stress materials. For a given set of parameters, this model allows to match consistently transient and steady state features of driven disordered systems under both applied shear-rate and creep protocols.
