论文摘要
赫歇尔 - 布尔克利法（Herschel-Bulkley Law）是一种普遍的构成关系，在经验上已知适用于包括剪切玻璃在内的各种软材料。尽管Herschel-Bulkley法律引起了公众的关注，但其结构性起源仍然是一个悬而未决的问题。在这封信中，通过对二进制Lennard-Jones眼镜的原子模拟，我们报告说，具有负特征值或所谓的想象模式的瞬时正常模式是Herschel-Bulkley风湿性玻璃中的Herschel-Bulkley流变学的结构信号。
The Herschel-Bulkley law, a universal constitutive relation, has been empirically known to be applicable to a vast range of soft materials, including sheared glasses. Although the Herschel- Bulkley law has attracted public attention, its structural origin has remained an open question. In this letter, by means of atomistic simulation of binary Lennard-Jones glasses, we report that the instantaneous normal modes with negative eigenvalues, or so-called imaginary modes, serve as the structural signatures for the Herschel-Bulkley rheology in sheared glasses.
