The strength values are comparable to determinations of uniaxial compressive strength tests of Westerly granite, which range from 130 MPa to 210 MPa (Heard and others, 1974) The slopes of best-fitting lines to the elastic portions of the stress-strain data from the strength experiments were taken for the values of Young's modulus

2020-6-1 For granite, the fracture dip angles of the specimens are greater than 80° where σ 2 ≥ 50 MPa at σ 3 = 10 MPa, σ 2 ≥ 150 MPa at σ 3 = 20 MPa, and σ 2 ≥ 300 MPa at σ 3 = 30 MPa. Under these stress conditions, the fracture orientations in the granite specimens are distributed approximately along the σ 1 σ 2 plane, which is similar to slabbing failure.

2018-6-21 Knowledge of the strength and elastic modulus of a reservoir rock is important for the optimisation of a particular geothermal resource. The reservoir rock for many geothermal projects in the Upper Rhine Graben, such as those at Soultz-sous-Forêts and Rittershoffen (both France), is porphyritic granite. High fracture densities (up to ~ 30 fractures/m) in this reservoir rock require that we
