    Hoek-Brown material model

    Application PLAXIS 2D
    Version PLAXIS 2D 2015
    Date created 27 December 2016
    Date modified 27 December 2016

    This document verifies that the Hoek-Brown model is correctly implemented in PLAXIS. For that purpose, the elasto-plastic behaviour of a rock mass is studied via a circular opening subjected to in situ stress in generalized Hoek-Brown material ( α ≥ 0.5 ). PLAXIS results are verified against the closed form solution presented by Carranza-Torres (2004).

    Validation - Hoek-Brown material model - geometry

    It is concluded that the results are in good agreement and the Hoek-Brown model is correctly implemented in PLAXIS.
