Professor Ronaldo Borja: Deformation and failure processes in geologic materials at scales from grains to basins

12th March 2008, 17:15 to 18:15, Lecture room 21, Palace Green (Union Society)

Sediments and sedimentary rocks display a wide range of deformation and failure processes and structural styles that reflect their porous and granular nature, variable loading conditions and loading rates in active depositional settings, and complex chemical/mechanical water-sediment-rock interactions. A basic understanding of these multiscale deformation and failure processes is a prerequisite for successful energy and water resource management and natural hazard mitigation.

In keeping with the IAS sub-theme on multiscale modeling, Professor Borja will cover some of the engineering and geoscience research activities conducted at Stanford University focusing on theoretical, numerical and computational aspects of deformation and failure processes in sediments and rocks across a wide range of scales. “Multiscale” in the present context refers to the physical scale of the problem of interest, which may range from granular scale controlling the behavior of small sediment samples tested in the laboratory, to basin scale encountered in the simulation of faulting and folding of rocks, as well as in the studies of mountain building. Professor Borja will present some advanced numerical techniques that his group uses to model the complex deformation and failure processes from micron-scale to kilometer-scale. An example includes preserving the numerical resolution of a centimeter-scale rock fracture superimposed over a kilometer-scale rock fold.

Professor Borja is a professor in the Department of Civil and Environmental Engineering at Stanford University. He is visiting Durham as an IAS Distinguished Fellow from 17 February - 31 March 2008.
