Temperature-dependent mechanical behaviour of Australian Strathbogie granite with different cooling treatments
W.G.P. Kumari,Pathegama Gamage Ranjith,Mandadige Samintha Anne Perera,Mandadige Samintha Anne Perera,Bernard Chen,Ilmutdin M. Abdulagatov +5 more
TL;DR: In this article, the effect of increasing temperature (from room temperature to 800 °C) followed by two cooling methods (both rapid and slow) on the mechanical behavior of Australian Strathbogie granite under uniaxial conditions was investigated.

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.

Hydraulic fracturing under high temperature and pressure conditions with micro CT applications: Geothermal energy from hot dry rocks
W.G.P. Kumari,Pathegama Gamage Ranjith,Mandadige Samintha Anne Perera,Mandadige Samintha Anne Perera,Li Xueqin,Linge Li,Bernard Chen,B.L. Avanthi Isaka,V.R.S. De Silva +8 more
TL;DR: In this article, the authors investigated the effect of reservoir depth, temperature, and sample heterogeneity during hydraulic fracturing and the influences of rock micro-structure on fracture propagation in deep geothermal reservoirs.

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.

Mechanical behaviour of Australian Strathbogie granite under in-situ stress and temperature conditions: An application to geothermal energy extraction
W.G.P. Kumari,Pathegama Gamage Ranjith,Mandadige Samintha Anne Perera,Shi Shi Shao,Bernard Chen,Aref Lashin,N. Al Arifi,Tharaka Dilanka Rathnaweera +7 more
TL;DR: In this paper, the authors investigated the stress-strain behavior under in-situ stress and temperature conditions by conducting a series of high-pressure, high-temperature triaxial experiments on Australian Strathbogie granite under four different confining pressures (10, 30, 60, 90 MPa) and four different temperatures (RT, 100, 200, 300 °C).
