Laboratory of Experimental Rock Mechanics LEMR

The Laboratory of Experimental Rock Mechanics (LEMR) at EPFL, under the direction of Prof. Marie Violay, belongs to the School of Architecture, Civil and Environmental Engineering (ENAC).

The LEMR conducts research on the mechanical behaviour, physical and fluid transport properties of rock materials at sub-surface conditions. This is accomplished by means of experimental research coupled with microstructural studies of the micro-scale processes, and modelling of these processes.

The LEMR provides research, teaching and services related to rock mechanics, rock physics, and engineering geomechanics.
