A session on Instabilities and multi-physical processes in geomaterials (Session ID: 81743) is going to be held at the American Geophysical Union (AGU) Fall Meeting on 9-13 December 2019 in San Francisco. Abstract submissions are open and the deadline for all submissions is Wednesday, 31 July at 23:59 EDT.

We look forward to receiving your abstract.

Session Description:
There is an increasing understanding in the scientific community that multi-physical mechanisms are present and fundamental to understand the behavior of Geomaterials at natural conditions. When at depth for example, high temperatures and pressures can activate different coupled mechanisms at the origin of instabilities like strain localization, fracture, etc. In addition, the high velocities reached during seismic slips also involve various mechanisms that are difficult to observe and understand. Finally, operational Geomechanics for energy extraction and storage are increasingly facing challenges that require multi-physical considerations to be solved. Examples include unconventional energy production, Geothermal, CO2 storage and nuclear waste disposal, with particular emphasis required in studying the interaction of a fluid with Geomaterials in chemically active conditions. In this session we aim at convening contributions dealing with all (numerical, theoretical, experimental, in-situ) aspects of geomaterials, emphasizing the role of multi-physical effects in the response and stability of Geomaterials.
