Barodesy (Kolymbas, Medicus, Schneider-Muntau, Fellin)
Barodesy is a constitutive model for granular media and does not use standard notations of elasto-plasticity, e.g. yield function, flow rule or plastic potential. Barodesy is formulated (like hypoplasticity) in one single rate equation to describe incremental soil response, i.e. the objective stress rate as a function of the actual effective Cauchy stress, the stretching and the void ratio. The User Subroutine is developed for barodesy for clay according to Medicus and Fellin (2017). Applications of the ABAQUS User Subroutine have been published in Schneider-Muntau et al. (2017) and Schneider-Muntau et al. (2017).
