Coupled Thermo-Hydro-Mechanical Processes in Fractured Rock Masses: Discrete Element Modeling and Engineering Applications

Author Biography

Fengshou Zhang is a distinguished professor in the Department of Geotechnical Engineering at Tongji University, Shanghai, China. He obtained his Ph.D. from the Georgia Institute of Technology in 2012. After that, he worked at Itasca Consulting Group, Inc., for a few years as a geomechanics engineer providing consulting services to the oil and gas industries, before he joined Tongji University in 2016. His research direction is multi-field coupling of rock mechanics and its application in deep earth engineering such as shale gas, dry hot rock and carbon sequestration. He has more than 150 published papers and won the Future Leaders Award (2015) and the Early Career Award (2018) of American Society of Rock Mechanics (ARMA), the first Qian Qihu Award (2020) of Chinese Society of Rock Mechanics and Engineering (CSRME) and the 17th China Youth Science and Technology Award (2022). Branko Damjanac is a senior principal engineer at Itasca Consulting Group, Inc. He obtained his Ph.D. in rock mechanics from the University of Minnesota in 1996. He has experience in the design and analysis of underground excavations for oil storage and waste isolation. He has been involved in stability analyses of underground and open-pit mines in both hard and soft rocks. He has developed a 3D numerical model to simulate the coupled hydro-mechanical response of a fluid-saturated rock mass. Dr. Damjanac was involved in a number of projects in the petroleum, geothermal and mining industries with the objective of design and operation optimization of rock mass treatment by fluid injection. Jason Furtney is the chief technical officer of Itasca. He has a bachelor's degree in Geology from the University of Edinburgh and a Ph.D. in applied fluid mechanics from the University of Cambridge. He joined Itasca Consulting Group, Inc., in 2006 and has worked on areas including numerical modeling of mechanical behavior, fluid flow and heat transfer in earth materials. He specializes in novel solutions to complex engineering problems including mathematical and numerical modeling and machine learning. His project work includes rock blasting, solution mining, nuclear waste isolation, mining geomechanics and enhanced geothermal systems.
