IC MAGE Model 14 – bounding surface plasticity model for sands under static and cyclic loading

Authors/Creators

  • 1. Imperial College London

Description

IC MAGE M14 is a user-defined model for PLAXIS built using the IC MAGE UMIP framework. This model is based on the bounding surface plasticity model by Manzari & Dafalias (1997), subsequently expanded by Papadimitriou & Bouckovalas (2002) and Taborda et al. (2014). It focuses on providing a flexible and modular approach to bounding surface plasticity modelling of sand behaviour, both under monotonic and cyclic loading conditions.
