On the Tensile Strength of Granite at High Strain Rates considering the Influence from Preexisting Cracks Mahdi Saadati, 1,2 Pascal Forquin, 3 Kenneth Weddfelt, 2 and Per-Lennart Larsson 1
Generally, sedimentary rocks can range from weak to medium (10-80 MPa), and igneous rocks range from medium to very strong (40-320 MPa). The highest unconfined compressive strength observed in a rock is on the order of 400 MPa (e.g. nephritic jade).
At high strain rates, the ultimate strength is deterministic and is obtained from the DFH model as a function of the Weibull parameters as where is the medium dimension (in 3D) and a characteristic stress as It should be mentioned that the DFH model predicts the granite tensile strength at the strain rate of 70 1/s (the same strain rate as in ...

The borehole should break under pore pressure about 5 MPa, not need pump pressure at all, if it was poured with water. The borehole of Ertan at a depth of 30 m would crack after drilling, for the magnitudes of 3σ h − σ H is low to −9 MPa, about the tensile strength of surrounding rocks.

When exploiting the deep resources, the surrounding rock readily undergoes the hole shrinkage, borehole collapse, and loss of circulation under high temperature and high pressure. A series of experiments were conducted to discuss the compressional wave velocity, triaxial strength, and permeability of granite cored from 3500 meters borehole under high temperature and three-dimensional stress ...
Uniaxial compressive strength (UCS) is a key physical test relevant to iron ore crusher design and rock geomechanics for mining. Tests are typically performed on intact lengths of NQ, HQ, or PQ diamond drill core and record the maximum axial load sustained at the point of failure.
These properties have made granite a widespread construction stone throughout human history. The average density of granite is between 2.65 and 2.75 g/cm 3 (165 and 172 lb/cu ft), its compressive strength usually lies above 200 MPa, and its viscosity near STP is 3–6·10 19 Pa·s.
