Simple Matlab driver running elasto-plastic and hypoplastic models. Rather an education tool than a serious calibration software, but some may find it useful to familiarize with the structure of constitutive model equations and to run simple element test simulations.
The SoilTest option is a quick and convenient procedure to simulate basic soil lab tests. It also offers the possibility to optimise model parameters. It works for any model, both standard soil models as well as user-defined models.
A dedicated special purpose incremental driver which is able to calculate the results of homogeneous experiments. Both displacement controlled and force controlled experiments can be performed.
ExCalibre is online tool for automatic calibration of soil constitutive models, adopting a unique model-specific calibration algorithm respecting physical meaning of material parameters. Experimental data are read from a simple Excel spreadhseet template.
Incremental Driver is a single element code developed by Andrzej Niemunis (2007, 2014) for running element tests using constitutive models implemented in umat format.
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.
