ISA is a mathematical extension of conventional hypoplastic models for soils to improve simulations of cyclic loading. It can be considered as a reformulation of the conventional intergranular strain theory by Niemunis and Herle (1997).
A PhD-level course on hypoplastic constitutive modelling intended for both academia and practitioners.

Number of interesting news at SoilModels from past week: New Barodesy constitutive model, umat with source code and Plaxis DLL. Thanks to the researchers from the University of Innsbruck (Barbara […]
Barodesy is a constitutive model for granular media and does not use standard notations of elasto-plasticity, e.g. yield function, flow rule or plastic potential.
SANISAND is an advanced elasto-plastic model based on a concept of rotational hardening incorporating the effects of fabric-dilatancy.
Sand hypoplastic model is an advanced incrementally non-linear constitutive model for sand, an outcome of an extensive research at Karlsruhe University in 1990's.
Clay hypoplasticity is an advanced incrementally non-linear constitutive model based on critical state soil mechanics developed specifically for simulation of fine-grained materials.
Download package of a Incremental Driver single element program by Niemunis (2007, 2014) for running element tests using constitutive models implemented in umat format.
