Implementation of a Modified Anisotropic Creep Model for Clays with Use of the Physics Builder

M. Karlsson [1], J. Yannie [1],
[1] Chalmers University of Technology, Gothenburg, Sweden

In this work a modified anisotropic creep model with structure for soft soils was implemented by using the Physics Builder. The model is validated against boundary value laboratory test such as undrained tri-axial tests and CRS (constant rate of strain) tests. The implemented user-defined MAC-s constitutive model seems to capture many of the important behaviors seen in soft soils.
