Abstract. DEM simulations by Chialvo et al. observed three distinct flow regimes for homogeneous simple shear of soft, frictional, noncohesive spheres in different domains of shear rate and density. This paper shows that all three regimes can be accommodated in a continuum description, using the CIDR formalism.

包括 Chialvo 等人的三种流动状态在内的粒状流构成关系

SIAM 应用数学杂志》第 84 卷第 2 期第 621-631 页，2024 年 4 月。摘要。Chialvo 等人的 DEM 模拟观察到，在不同的剪切速率和密度域中，软、摩擦、非粘性球体的均匀简单剪切有三种截然不同的流动状态。本文表明，利用 CIDR 形式，所有这三种状态都可以用连续介质描述。

期刊介绍： SIAM Journal on Applied Mathematics (SIAP) is an interdisciplinary journal containing research articles that treat scientific problems using methods that are of mathematical interest. Appropriate subject areas include the physical, engineering, financial, and life sciences. Examples are problems in fluid mechanics, including reaction-diffusion problems, sedimentation, combustion, and transport theory; solid mechanics; elasticity; electromagnetic theory and optics; materials science; mathematical biology, including population dynamics, biomechanics, and physiology; linear and nonlinear wave propagation, including scattering theory and wave propagation in random media; inverse problems; nonlinear dynamics; and stochastic processes, including queueing theory. Mathematical techniques of interest include asymptotic methods, bifurcation theory, dynamical systems theory, complex network theory, computational methods, and probabilistic and statistical methods.
