From Elasticity to Hypoplasticity: Dynamics of Granular Solids
Yimin Jiang, Mario Liu
TL;DR
This paper develops a hydrodynamic theory for granular solids that extends traditional elasticity to include slow grain deformation, aligning well with soil mechanics models.
Contribution
It introduces a generalized theory of granular elasticity incorporating grain deformation effects, bridging static and dynamic behaviors.
Findings
The theory matches well with existing soil mechanics models.
It effectively describes the dynamics of granular solids under slow deformation.
Provides a unified framework for static and dynamic granular behavior.
Abstract
"Granular elasticity," useful for calculating static stress distributions in granular media, is generalized by including the effects of slowly moving, deformed grains. The result is a hydrodynamic theory for granular solids that agrees well with models from soil mechanics.
