Predicting the Elastic Properties of a Cemented Granular Material during Chemical Damage (Debonding)
Alexandre Sac-Morane, Maria Olarte-Garzon, Philipp Braun +3
While underground reservoirs emerge as essential elements to face global warming, these systems represent complex multi-physical and multiscale problems. The considered injection o…
Predicting cement microstructure and mechanical properties in hydrating cement paste with a Phase-Field model
Alexandre Sac-Morane, Katerina Ioannidou, Manolis Veveakis +1
Predicting the evolving microstructure of hydrating cement is essential for understanding and modeling its mechanical property development. Physics-based continuum approaches offer…
Importance of precipitation on the slowdown of creep behaviour induced by pressure-solution
Alexandre Sac-Morane, Hadrien Rattez, Manolis Veveakis
Pressure-solution is a chemo-mechanical process, involving dissolution at grain/asperity contacts and precipitation away from them. It induces a compaction in time of rocks and sed…
Stress state evolution of a cemented granular material subjected to bond dissolution by Discrete Element Modeling
Alexandre Sac-Morane, Hadrien Rattez, Manolis Veveakis
Rock weathering is a common phenomenon in most engineering applications, such as underground storage or geothermal energy. This work offers a discrete element modelization of the p…
Frictional weakening of a granular sheared layer due to viscous rolling revealed by Discrete Element Modeling
Alexandre Sac-Morane, Manolis Veveakis, Hadrien Rattez
Considering a 3D sheared granular layer modeled with discrete elements, it is well known the rolling resistance significantly influences the mechanical behavior. Even if the rollin…
A Phase-Field Discrete Element Method to study chemo-mechanical coupling in granular materials
Alexandre Sac-Morane, Manolis Veveakis, Hadrien Rattez
This paper presents an extension of the discrete element method using a phase-field formulation to incorporate grain shape and its evolution. The introduction of a phase variable e…
