Timelapse ultrasonic tomography for measuring damage localization in geomechanics laboratory tests.

Variation of mechanical properties in materials can be detected non-destructively using ultrasonic measurements. In particular, changes in elastic wave velocity can occur due to damage, i.e., micro-cracking and particles debonding. Here the challenge of characterizing damage in geomaterials, i.e., rocks and soils, is addressed. Geomaterials are naturally heterogeneous media in which the deforma...

Cavity Expansion Methods in Geomechanics

International Workshop of Young Doctors in Geomechanics

The objective of the present project was to study how high temperatures affect the different mechanical parameters of chalks. The general result is that both cohesion and the hydrostatic yield stress are typically reduced about 20 % in going from 20 to 130 C, but the magnitude of this reduction may be chalk type dependent.
