Abstract
AbstractThis paper presents the automatic parameter calibration of two advanced constitutive models for sand: Hypoplasticity with Intergranular Strain and Sanisand. The application of the software is demonstrated by automatically calibrating the parameters for Karlsruhe Sand using data of oedometric compression and drained monotonic triaxial tests. The quality of the obtained parameter sets is demonstrated by the comparison of the experimental data with simulations, using 1) the automatically calibrated material parameters and 2) two reference parameter sets calibrated “by hand”. It is shown that the developed calibration software outperforms the “by hand” calibration in terms of accuracy, simplifies the parameter calibration and lowers the entry hurdle for the use of the advanced constitutive models.KeywordsAutomatic parameter calibrationSoil modelsHypoplasticitySanisand
