Implementation (umat.for) of a model published in Mugele, L., Stutz, H. H. and Mašín, D. (2024). Generalized intergranular strain concept and its application to hypoplastic models. Computers and Geotechnics 173, September 2024, 106480.
Various extensions of the original concept of intergranular strain (IS) according to Niemunis and Herle (1997), to account for small strain effects in constitutive models, have developed in recent years.
This page (which is currently under construction) is intended to provide an overview of existing intergranular strain extensions combined with corresponding implementations.
