Dense suspensions and supercooled, glass-forming, fragile Lennard-Jones liquids near T(g) should display similar relaxational and rheological behavior based on dynamical heterogeneities (actually, clusters of correlated, mobile particles embedded among the ordinary, bulk particles). Near structural arrest, we expect the shear-thinning onset to vanish as the inverse bulk-beta relaxation time. Connection to mechanical properties of granular media near random loose packing is briefly considered.
基于动力学不均匀性(实际上是嵌入普通大量粒子中的相关移动粒子簇),致密悬浮液以及接近玻璃化转变温度(T(g))的过冷、形成玻璃的、易碎的 Lennard-Jones 液体应表现出相似的弛豫和流变行为。在接近结构停滞时,我们预计剪切变稀起始点会随着体相β弛豫时间的倒数而消失。简要考虑了与随机松散堆积附近颗粒介质力学性质的联系。
