Calibration of the hardening soil model in excalibre
Abstract
The hardening soil model is one of the most commonly used constitutive models in engineering practice. This model is based on multi-surface plasticity and combines the well-known Mohr-Coulomb failure criterion, a hardening shear surface and a cap yield surface into a single model. The stress-strain behaviour is improved by including nonlinear elasticity. In this paper a calibration tool for a modified version of the hardening soil model is presented which is currently implemented in the online calibration application called ExCalibre.
