Modeling of brittle failure based on a Hoek & Brown yield criterion: parametric studies and constitutive validation

Hoek & Brown (HB) failure criteria have been employed over the past decades in common engineering applications due to their extended capability to capture the non-linear yielding of different types of rocks. Often implemented within a perfect plastic framework, this constitutive approach is here enhanced by introducing a softening rule to...

A Constitutive Model For Masonry Structures: Practical Application Under Earthquake Loading In Groningen

In this paper, a constitutive model for masonry structures is presented. It is based on the Jointed Rock (JR) model with overall Mohr-Coulomb (MC) failure criterion, and it is implemented as a user-defined soil model in the finite element<br/>code PLAXIS. The Masonry model is a linear elastic-perfectly plastic model capable of simulating the...

Implementation, Validation, and Application of PM4Sand Model in PLAXIS

This paper presents the implementation, validation, and application of the PM4Sand model (version 3) formulated by Boulanger and Ziotopoulou (2015) in the PLAXIS finite element code. The model can be used for modelling geotechnical earthquake engineering applications, especially in the case liquefaction is likely to occur. The PM4Sand model...
