Study of Damage Constitutive Model of Brittle Rocks considering Stress Dropping Characteristics
Advances in Civil Engineering, 2020 Deep brittle rock exhibits characteristics of rapid stress dropping rate and large stress dropping degree after peak failure. To simulate the whole process of deformation and failure of the deep brittle rock under load, the Lemaitre strain equivalent ...

Implementation of the Quasi-Brittle Damage Model for 2024 Aluminum Alloy under Periodic Loading [PDF]
International Journal of Advanced Design and Manufacturing Technology, 2019 Damage mechanics is one of the most important parts of mechanical engineering that determines the time life for different mechanical elements. The most various models that have been provided so far in damage mechanics, are related to ductile or brittle ...

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

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 ...

Pore space and brittle damage evolution in concrete [PDF]
Engineering Fracture Mechanics, 2013 AbstractA novel lattice model is proposed for linking experimentally measured porosity of concrete to damage evolution and the emergent macroscopic behaviour. Pore sizes are resolved by X-ray CT and distributed at lattice bonds. The mechanical behaviour of bonds is elastic-brittle with failure criterion dependent on local forces and pore sizes.
