Geomechanics Module
For users of the Geomechanics Module, COMSOL Multiphysics® version 5.5 brings a mean-stress-based tension cut-off criterion and three new tutorial models. Browse these geomechanics features and more below.
Mean Stress Tension Cut-Off Criterion
In the Mohr–Coulomb and Drucker–Prager models for soil plasticity, a mean-stress-based tension cut-off criterion has been added. This method for suppressing tensile stresses is more stable from a numerical point of view.
