Title

A hypoplastic model for sand

Description

The implemented model has been published by von Wolffersdorff (1996). The implementation also contains Niemunis and Herle (1997) extension for predicting small strain stiffness effects.

Authors

The original umat implementation has been developed by Claudio Tamagnini in 2005. It has since been further developed and updated to new models by David Mašín.
