Estimating in situ rock mass strength ... .

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 SoultzsousForêts and Rittershoffen (both France), is porphyritic granite. High fracture densities (up to ~ 30 fractures/m) in this reservoir rock require that we ...

ASTM Test Results | Select Stone

Compressive Strength. Compressive Strength is the stress, in pounds per square inch (psi) that will rupture a stone sample. Very rarely is the compressive strength of a stone much of a factor in stone selection. A column of stone with a density of 160 lbs/cf that is 100 feet tall exerts a compressive stress of only 110 pounds per square inch.

Experimental study on granite and the .

Then eliminating the dynamic compressive strength increment caused by both the lateral inertial effect and end friction effect from the measured dynamic compressive strength of granite, the true strainrate effect of granite in SHPB tests is determined. And the reliability of the obtained true strainrate effect is verified. In addition, the numerical method can be used to determine the true ...
