Sheng-Qi Yang,Pathegama Gamage Ranjith,Pathegama Gamage Ranjith,Hong Wen Jing,Wen Ling Tian,Yang Ju +5 more
TL;DR: In this paper, the effect of high temperature treatments (200, 300, 400, 500, 600, 700 and 800) on the crack damage, strength and deformation failure behavior of a granite was investigated.

Temperature influence on the physical and mechanical properties of a porous rock: San Julian's calcarenite
TL;DR: In this paper, the authors presented a study that has been funded by the Universidad de Alicante under the projects uausti11-11, VIGROB-212 and gre09-40 and by the Generalitat Valenciana under the project gv/2011/044.
Journal ArticleDOI
An experimental study on the physico-mechanical properties of two post-high-temperature rocks
TL;DR: In this paper, a hydraulic servo pressure testing machine was used to investigate the physical and mechanical properties of two types of rock types, namely, granite and sandstone, after high-temperature treatment.
Journal ArticleDOI
Experimental and numerical studies on the mechanical behaviour of Australian Strathbogie granite at high temperatures: An application to geothermal energy
TL;DR: In this article, the effect of temperature on the mechanical behavior of Strathbogie granite (fine-grained) was studied under unconfined stress conditions, and the results showed that the increasing temperature reduces the stress thresholds for crack initiation and crack damage and extends the duration of stable crack propagation.
Journal ArticleDOI
Effect of cooling rate on the mechanical behavior of heated Strathbogie granite with different grain sizes
TL;DR: In this paper, the authors found that either grain size or porosity can individually affect the stress at which new cracks are initiated at different cooling stages, and that slowly cooled rock specimens have longer stable crack propagation regions than rapidly cooled rocks.

Fault rocks and fault mechanisms
TL;DR: In this paper, physical factors likely to affect the genesis of the various fault rocks are examined in relation to the energy budget of fault zones, the main velocity modes of faulting and the type of fault, whether thrust, wrench, or normal.

Experimental Rock Deformation: The Brittle Field
TL;DR: In this article, the Griffith Theory of Brittle Failure and the evolution of physical properties during brittle failure are discussed, including the role of pore fluid and friction and sliding phenomena.
Journal ArticleDOI
Fault zone models, heat flow, and the depth distribution of earthquakes in the continental crust of the United States
TL;DR: In this article, the authors show that the maximum depth of microseismic activity in various heat flow provinces of the conterminous United States generally correlates well with the frictional to quasi-plastic transition modeled for the different geotherms.

Experimental deformation of partially-melted granite
I. van der Molen,M. S. Paterson +1 more
TL;DR: In this article, an account of the experimental deformation of partially-melted granite with melt fractions up to 25% at 800 °C and 300 MPa confining pressure in constant strainrate tests between 10−3 and 10−6 S−1, creep tests and cycling tests is given.
