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.
FLAC 3D, Fast Lagrangian Analysis of Continua in 3D, is numerical modeling software for advanced geotechnical analysis of soil, rock, groundwater, and ground support. It utilizes an explicit finite difference formulation.
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.
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.
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.
Tochnog Professional is a free 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.
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.
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.
GroundVib performs semi-analytical analysis of wave propagation in layered soil using the Green's function for layered soil. The transmission loss is evaluated at selected distances in the frequency range up to 250 Hz.
