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…
Strain localization regularization and patterns formation in rate-dependent plastic materials with multiphysics coupling
Antoine B. Jacquey, Hadrien Rattez, Manolis Veveakis
Strain localization is an instability phenomenon occurring in deformable solid materials which undergo dissipative deformation mechanisms. Such instability is characterized by the…
Contact phase-field modeling for chemo-mechanical degradation processes. Part I: Theoretical foundations
Alexandre Guevel, Hadrien Rattez, Sotiris Alevizos +1
As phase-field modeling (PFM) is booming across various disciplines and has been proven fitted for numerically modeling interfacial problems, we aim at taking a step back to revisi…
Contact phase-field modeling for chemo-mechanical degradation processes. Part II: Numerical applications with focus on pressure solution
Alexandre Guevel, Hadrien Rattez, Manolis Veveakis
The microstructural geometry (MG) of materials has a significant influence on their macroscopic response, all the more when the process is essentially microscopic as for microstruc…
