IC MAGE M08 is a user-defined model for PLAXIS built using the IC MAGE UMIP framework which combines a Mohr-Coulomb failure criterion with a modified version of the IC.G3S isotropic small strain stiffness model and the nonlinear scaling factor proposed by Taborda & Zdravkovic (2012). It allows for the generation of hysteresis (and energy dissipation) by adopting a cyclic nonlinear elastic framework. The elastic part of the model allows the use of independent variations of constrained modulus, with its degradation depending on the vertical strain, and the shear modulus, which depends on the deviatoric strain.
