DIANA (DIsplacement ANAlyzer) is an extensive multi-purpose finite element software package that is dedicated, but not exclusive, to a wide range of problems arising in Civil engineering including structural, geotechnical, tunnelling, earthquake disciplines and oil & gas engineering.
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.
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.
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.
SIGMA/W is a powerful finite element software product for modeling stress and deformation in earth and structural materials. SIGMA/W analyses may range from simple linear elastic simulations to soil-structure interaction problems with nonlinear material models.
Tochnog Professional is a Finite Element program offering a wide variety of geotechnical and mechanical options; modern material laws including the most recent rate independent and viscous hypoplasticity models.
