The contribution deals with the mathematical modelling of hypoplasticity of granular materials. The problem of stress-controlled hypoplasticity with a cyclic proportional loading and unloading of drained granular material under different anisotropic settings is considered, and a gradual compaction of the material, called ratchetting, is investigated together with the influence of uncertain input parameters on the model outputs, namely the strain components in the material in its limit (i.e. compacted) state. The uncertainty quantification is presented through 3D graphs. The depicted data also allows for a fuzzy set interpretation.
