Plasto-damage modelling for semi-brittle geomaterials
E3S Web of Conferences, 2016 This paper presents an elastoplastic damage model for constitutive modelling of semi-brittle geomaterials showing two irreversible mechanisms. On one hand, the model deals with the plastic behaviour of a porous medium by a new variant of Barcelona Basic ...

Predicting excavation damage zone depths in brittle rocks
Journal of Rock Mechanics and Geotechnical Engineering, 2016 During the construction of an underground excavation, damage occurs in the surrounding rock mass due in large part to stress changes. While the predicted damage extent impacts profile selection and support design, the depth of damage is a critical aspect
