Please join us for a special seminar as Dr. Chloe Arson from the Georgia Institute of Technology will present her work on the “Thermodynamics of Rock Damage and Energy Applications” on Wednesday, May 22th, 2013 at 1:00 pm – 2:30 pm. The seminar will be held in Duckering 531.

About the Presententation:
Continuum Damage Mechanics (CDM) was designed to model the behavior of brittle solids such as metals. Poro-mechanics is appropriate to model the interactions between a solid matrix and multiple fluid phases contained in a connected porous network. Both theories resort to the concept of internal length, which represents the typical size of the material heterogeneities and scales the Representative Elementary Volume (REV). Damage and healing prediction relies on the field variables chosen to describe the anticipated “degradation” and “recovery”. A thermodynamic analysis is proposed to model the effects of crack opening, closure and rebonding on rock stiffness and permeability.

About the Presenter:
Dr. Arson graduated from Ecole Nationale des Ponts et Chaussées (France) in 2009. Her Ph.D. project aimed to study the Excavation Damaged Zone around nuclear waste disposals and was funded by EURATOM, the European Atomic Energy Community. Between 2009 and 2012, Dr. Arson worked as an Assistant Professor in the Department of Civil Engineering at Texas A&M University. She joined the Geosystems Group at Georgia Tech in August 2012. Dr. Arson’s research focuses on the theoretical and numerical modeling of damage in porous media and granular assemblies. The main applications are: particle crushing, hydraulic fracturing, geothermal systems and deep geological storage (including nuclear waste disposals, carbon dioxide sequestration and compressed air storage).
