Title
Intergranular Strain Extensions
Description
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.
Simulation Software Offering This Model
The Abaqus Unified FEA product suite offers powerful and complete solutions for both routine and sophisticated engineering problems covering a vast spectrum of industrial applications.
Calibration Software Offering This Model
Triax is an inhouse element test constitutive model driver developed since 2001 at Charles University and elsewhere by David Mašín and coworkers. It covers wide range of constitutive models and testing conditions.
Incremental Driver is a single element code developed by Andrzej Niemunis (2007, 2014) for running element tests using constitutive models implemented in umat format.
