Dr. M.H.B. (Farzine) Nasseri has a Ph.D. in rock mechanics, and is a licensed Professional Engineer in Ontario. He has 20 years of research, teaching and consulting experiences in the field of rock mechanics. His research interest involves in understanding the factors affecting fracture initiation and propagation under various stress regimes and scales. Characterization of petrofabric structures, evaluation of fracture toughness of rocks, measurements of fluid flow and transport properties in rocks and laboratory acoustic/seismic velocities measurements and their analysis are some of the tools used by him to explore the interdisciplinary relationship among the rock mechanics, rock physics and engineering seismology.

At the largest scale, fractures give rise to volcanoes and earthquakes and at engineering scales they form pathways for fluids to flow through and reduce the strength of rock. For these reasons, the study of rock fractures has been a major focus of research in the mining, petroleum and civil engineering industries for decades. To… Read more »
The demand for underground radioactive waste repositories makes the study of thermo-hydro-mechanical (THM) processes in rocks an increasingly important topic. In collaboration with the Nuclear Waste Management Organization (NWMO) we conducted triaxial deformation experiments on Cobourg limestone, an argillaceous sedimentary rock found in Southern Ontario, Canada. Experiments were conducted at a constant confining pressure of 12.5 MPa where… Read more »
The heart of the Rock Fracture Dynamics Facility is a technologically advanced true-triaxial computer controlled rock deformation system with integral permeability measurement and geophysical imaging capability. For the first time, it is possible to carry out multi-axis thermo-mechanical, geophysical, and hydrological measurements essentially simultaneously on rock specimens ranging from hard rock such as granite to weak rocks undergoing… Read more »
Hydraulic fracturing is the initiation and propagation of a fracture by means of fluid pressurization. Hydraulic fracturing has grown in popularity over the past couple of decades in response to increasing public demand for energy alternatives, the discovery of large oil and gas reservoirs in North America and the growing demand for minerals. The objective… Read more »
