Dynamic Tensile Properties of Granite Varied with Depths

Based on the SHPB device, the dynamic tensile test was carried out on the granite, which is located at the depth 350 m∼580 m at the same borehole in TianHu area Xinjiang Province, the preselected site of the high-level radioactive waste geological disposal in China. Under the loading rate level of 10 5 MPa/s, the dynamic tensile strength is generally between 15 MPa∼35

Dynamic uniaxial compression tests on a granite — Monash

Dynamic uniaxial compression tests for the Bukit Timah granite in Singapore were conducted at four loading rates (10 0, 10 1, 10 3 and 10 5 MPa/s). It was found that the compressive strength increases from 205 MPa to 235 MPa with loading rate increasing from 10 0 to 10 5 MPa/s. Evidence also indicates that there are small changes in the Young's modulus and the Poisson's ratio of the granite

Failure properties of cubic granite, marble, and sandstone

Jun 01, 2020· The non-linear behavior before the peak strength point of granite became more apparent by the increase of σ 3, whereas σ 2 had an opposite effect on the non-linear behavior of granite under high σ 3 (e.g. 100 MPa). The non-linear behavior before the peak strength point was always found in marble and sandstone for all of the stress state

Failure properties of cubic granite, marble, and sandstone

Jun 01, 2020· Cubic specimens of granite, marble, and sandstone, with side lengths of 50 mm, were prepared in the laboratory. True triaxial compression tests were conducted on each rock type with minor principal stress (σ 3) magnitudes of 10, 20, 30, 50, and 100 MPa and the intermediate principal stress (σ 2) varying from σ 2 = σ 3 to σ 2 = σ 1 (where σ 1 represents the major principal stress).

Jan 14, 2020· pressure of the test system is 60 MPa, which is smaller than the compressive strength of the granite tested in this experiment. The gas pressure intensifier consists of a gas tank (3), gas pipes, and valves (6, 7, 10, 11) tighter with a gas pump (1) capable of increasing the gas pres-sure effectively from 0 to 3 MPa to 0–40 MPa.

Uniaxial Compressive Strength an overview

The major principal stress is horizontal with a magnitude of 3.4 MPa, and the compressive strength of the rock types is 53 MPa for the shale and 71 MPa for the basalt. The strength/stress ratio for these two cases is then 53/3.4 = 15.6 and 71/3.4 = 20.9, respectively, and

Natural stone strength (compression, bending, and abrasion

Jul 20, 2018· So, compressive strength is the highest load per unit area borne by the stone without giving in. A higher compressive strength between1,800 psi (12.45 MPa) and 19,000 psi (131 MPa) means the stone can endure an upper crushing load. Dry or wet conditions as per load determine the compressive strength of the stone. Bending strength test
