Description of Creep in Inherently Anisotropic Frictional Materials
Abstract
This paper presents a mathematical framework for modeling the creep phenomenon in frictional materials exhibiting a strong inherent anisotropy. The instantaneous time-independent response is described by invoking a plasticity framework which incorporates a scalar anisotropy parameter. The latter is a function of mixed invariants of the stress and microstructure tensors. The creep is assumed to be associated with progressive rearrangement of …
