Rocscience RSData
Strength & Stress Analysis of Rock and Soil Materials
Virtual Soil Mechanics Lab
Utilize constitutive models like NorSand and Modified Cam Clay to get an in-depth look into the stress-strain relationship of your soil materials.
Probabilistic Analysis
Perform probabilistic analysis to model the variability in rock unit weight, joint shear strength, and water pressure parameters and obtain location-specific probabilities of failure. Generate statistical plots like histograms, cumulative and scatter plots for any selection of blocks, and fit distributions and regression lines through the data.

RSData across Applications
Calibrate your rock’s strength criteria and observed stress-strain behaviours using field and lab test data and compare them against numerical simulations of the same tests.
Laboratory tests and stress-strain paths of soils can be imported into RSData for visualization. Compare & calibrate material parameters by plotting predicted constitutive behaviour on top of experimental data. RSData is a virtual soil mechanics lab, allowing you to study different constitutive models in prediction of typical laboratory tests.
Explore the latest features in RSData
Get in-depth insight into stress-strain behaviours and constitutive models of your materials.
Get the most control of your data by modifying value ranges, data sets and more. With stress path graphs, you can plot any two stress/strain or their invariants against each other.
Make your data come to life with the visualization of test progress and the evolution of hardening/softening rules in the constitutive models.
