Brittle-to-ductile fracturing transition: A chemo-mechanical phase-field framework
Fanyu Wu, Chong Liu, Manolis Veveakis +1
In chemically reactive environments, the mechanical integrity of geomaterials is fundamentally compromised by solid matrix dissolution. In this study, we propose a fully coupled ch…
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…
Probabilistic Spatial Interpolation of Sparse Data using Diffusion Models
Valerie Tsao, Nathaniel W. Chaney, Manolis Veveakis
The large underlying assumption of climate models today relies on the basis of a "confident" initial condition, a reasonably plausible snapshot of the Earth for which all future pr…
Learning Latent Hardening (LLH): Enhancing Deep Learning with Domain Knowledge for Material Inverse Problems
Qinyi Tian, Winston Lindqwister, Manolis Veveakis +1
Advancements in deep learning and machine learning have improved the ability to model complex, nonlinear relationships, such as those encountered in complex material inverse proble…
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…
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…
