IC MAGE M02 is a user-defined model for PLAXIS built using the IC MAGE UMIP framework which combines the state-parameter framework by Been & Jefferies (1985) with a Mohr-Coulomb failure criterion. The elastic response is given by the isotropic small strain stiffness model IC.G3S by Taborda et al. (2016). A reversal detection algorithm within a cyclic nonlinear elastic framework allows for the generation of hysteresis (and energy dissipation)., {"references":["Been, K. and Jefferies, M.G.

IC MAGE M09 is a user-defined model for PLAXIS built using the IC MAGE UMIP framework which combines the state-parameter framework by Been & Jefferies (1985) with a Mohr-Coulomb failure criterion. The elastic response is given by the isotropic small strain stiffness model IC.G3S by Taborda et al. (2016). A reversal detection algorithm within a cyclic nonlinear elastic framework allows for the generation of hysteresis (and energy dissipation). This model is the nonlocal version of IC MAGE M02., {"references":["Been, K. and Jefferies, M.G. (1985) A state parameter for sands.
