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.
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.

The Department of Mechanics, Faculty of Civil Engineering, Czech Technical University in Prague, has prepared a new training course for Ph.D. students, engineers interested in simulation and researchers who wish to quickly acquire the knowledge and practical skills necessary to employ OOFEM (an object-oriented open-source software package for solid mechanics, with extensions to fluid mechanics and transport problems). Participants will learn how to create, analyze and post-process models. Moreover, they will understand the OOFEM code structure and they will learn how to implement custom material models, elements, boundary conditions, or solvers.
The course takes place in Prague on 16-18 September 2019 and it will be delivered by a team of skilled OOFEM developers. No prior knowledge of OOFEM is required; however, a basic knowledge of C++ is highly recommended.
This course provides an overview of modeling approaches used in the mechanics of inelastic materials and structures, with special attention to objective description of highly localized deformation modes such as cracks or shear bands. It is one of the RILEM educational courses. The course is intended for graduate students at the doctoral level, but it can be equally useful to motivated master students, post-doctoral researchers, or senior researchers who are not specialists in this field.
September 3-5, 2019 – Autrans (Grenoble’s area, Alps, France)
Objectives : The combination of several risks and the associated domino effects are the subject of extensive research in engineering sciences, taking into account complex models. The consideration of the social dimensions of the management of these cascading risks is less developed. The challenge is both scientific, to take greater account of multidisciplinarity in the combined risk approach, and pragmatic, to manage crisis situations or take appropriate decisions to avoid the occurrence of other events.
The objective of this summer school is to provide an opportunity for doctoral students from the CDP Risk, as well as doctoral students and researchers from other universities, to exchange their scientific knowledge and experience on cascading phenomena.
Organized by the Risk interdisciplinary Research group of Grenoble.
