这项工作通过Kranz等人提出的瞬变形式主义推广了粒积分。[物理。莱特牧师。121,148002(2018年)10.1103/PhysRevLett.121.148002]以确定压力。我们将重点放在Bagnold区域，并为已在许多颗粒流动问题中成功应用的经验μ(I)流变学定律提供理论支持。特别是，我们确认，在μ(I)定律适用的区域内，颗粒间摩擦是不相关的。
This work generalizes the granular integration through transients formalism introduced by Kranz et al. [Phys. Rev. Lett. 121, 148002 (2018)10.1103/PhysRevLett.121.148002] to the determination of the pressure. We focus on the Bagnold regime and provide theoretical support to the empirical μ(I) rheology laws that have been successfully applied in many granular flow problems. In particular, we confirm that the interparticle friction is irrelevant in the regime where the μ(I) laws apply.
