SimpleSand
A Simple Sand Model
The continuum mechanics based sign convention (tension is positive) is used for consistency.
The SimpleSand
model is a simple sand hardening model that adopts a bounding surface concept.
Readers can also refer to the corresponding section in Constitutive Modelling Cookbook for details on the theory.
