Journal ArticleDOI
Coupled evolutions of fracture toughness and elastic wave velocities at high crack density in thermally treated Westerly granite
TL;DR: In this paper, a series of 20 chevron cracked notched Brazilian disc (CCNBD) samples of Westerly granite were failed in a standard Mode I tensile test at room temperature in order to evaluate the effect of thermal damage on fracture toughness.
Journal ArticleDOI
High‐velocity frictional properties of a clay‐bearing fault gouge and implications for earthquake mechanics
TL;DR: In this paper, the geophysical consequences of thermal dehydration of bonded water during seismic slip were investigated in the light of mineralogical and poromechanical data of several fault zones, which tend to show that this phenomenon has to be taken into account in most subsurface faults and in hydrous rocks of subducted oceanic crust.
Journal ArticleDOI
Dilatancy, compaction, and failure mode in Solnhofen limestone
TL;DR: In this paper, experiments were conducted on the Solnhofen limestone of intermediate porosity to investigate the interplay of dilatancy and shear compaction in controlling the brittle-ductile transition.
Journal ArticleDOI
Elastic wave velocities and permeability evolution during compaction of Bleurswiller sandstone
TL;DR: In this article, the authors studied the relationship between elastic wave velocities and volumetric strain in a set of deformation experiments of Bleurswiller sandstone and showed that although the three sets are correlated, they are not systematically correlated.
Journal ArticleDOI
Effects of pore collapse and grain crushing on ultrasonic velocities and Vp/Vs
TL;DR: In this article, the authors measured the elastic wave velocities and their ratio, Vp/Vs, along with porosity variations during wet and dry hydrostatic compaction of Bleurswiller sandstone, a 25% porosity Vosgian sandstone.
