Geosc598A: Geomechanics Seminar

2 Credits, Spring 2016

Prof. C. Marone and D. Elsworth
Penn. State University

Time: Friday 2:45-4:15 Room: 240 Deike

This is a reading seminar focused on current and foundational research contributions in Geomechanics, including ongoing work by current students. Topics will include selections from: Fault mechanics, fluid flow, poromechanics, nano-porosity connectivity, shale geomechanics, rheology, time-dependence of deformation, reservoir geomechanics, geothermal energy production, friction laws, strain localization, stability conditions for deformation, slow earthquakes and the spectrum of tectonic fault slip behaviors.

Participants will read assigned material, participate in choosing topics, lead discussion, and present results from their ongoing research. To facilitate discussion all participants are required to write a short summary (1 or 2 paragraphs) or critique of discussion papers. Please bring two copies of your summary to pass around during our discussion. Participants will be selected at random to lead discussions.
