摘要：
Granular materials show a wealth of interesting phenomena such as fluid-like behaviour and scale dependence. The description of these phenomena lies beyond the capability of conventional constitutive models. The paper discusses some high-order models within the framework of hypoplasticity. The high-order models are formulated by including the temporal and spatial derivatives of strain rate into the constitutive equation.
