IC MAGE Model 27 – Stochastic simple state-parameter dependent model with isotropic small strain stiffness

IC MAGE M27 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). It has been extended to allow the use of random fields to generate the initial distribution of void ratio, as well as safety analyses by factoring the angle of shearing resistance at Critical State and the cohesion intercept.
