Vinci Technologies | Unconfined compression system (UNIAXIAL .The Uniaxial Geotest 1000 system is a rock compression testing system capable of performing unconfined compression, bending, indirect tension, fracture, creep . properties in uniaxial compression can be determined, for example, compressive strength, static elastic constants (i.e. stress-strain curve, Young's modulus, and.**equipment and machine for unconfined compression tests on rock and modulus of elasticity**,Unconfined Compression Tester for Rocks Model TO . - Tinius OlsenThis equipment is used for determining unconfined compressive strength of intact rock core specimens. The rock sample is cut to length and the ends are machined flat. The specimen is placed in a loading frame and if required heated to the desired test temperature. Axial load is continuously increased on the specimen.

UNCONFINED COMPRESSION TEST AND YOUNG'S MODULUS ... EQUIPMENT. We will use a variety of devices in order to measure the geomechanical properties of rocks. It is important the user gets to know how each of these works in order to . or inside the machine, and never run the machine if there is a sample.

tests indicated that the rock within each rock type was quite uni- form. Results of the unconfined compressive strength tests on basalt indicated that as the loading rate was increased from 1 to 1.60 x 107 psi/sec, ultimate strength, total axial strain, and Young's modulus of elasticity increased. Total diametral strain decreased.

in testing procedures and minimum measurement equipment properties. . diameter is placed in the compression test machine and compressive . Rock samples can have uniaxial strength in the range from 5 MPa for soft rock, up to 250 MPa for very brittle rock. Concurrently, Young's modulus of elasticity is in the range.

Dec 7, 2015 . values of compressive strength may lead to over design of projects resulting in increased project costs. The UCS data obtained from the testing of rock cores is also used to calculate the Modulus of Elasticity. (Young's Modulus). Young's Modulus is a measurement of the force needed to stretch or compress.

Uniaxial compression testing: static elastic modulus (E ), static. Poisson's ratio (v ), uniaxial compressive strength (o ) and brittle- ness. - Brazilian disc testing: tensile strength (indirect test). - Triaxial testing: elastic modulus (E) and compressive strength (o). - Three point bending test: fracture toughness (K. ), elastic modulus.

Feb 20, 2018 . This study aims to numerically and experimentally investigate the response of a medium strength rock material under unconfined compression loading up to failure. . The undesired radial stresses appear due to different elastic properties of the steel of the testing machine platen and the rock specimen.

Push-button Up-Down-Stop operation with overtravel limit switch protection. • Highly versatile — can be used for Quick Undrained Triaxial, Unconfined Compression, CBR and Soil Cement testing with proper accessories. Shown with unconfined compression test digital readout set; not included, order separately.

method, an uniaxial compressive experiment was carried out on the rock samples of the same diameters with different heights, by using MTS electro-hydraulic servo testing machine to study the effect of sample heights on the uniaxial compressive strength of rocks and elastic modulus. The results of the experiment have.

1e3/s are processed with the method and compared to results of unconfined compression tests. It is found that the compressive behaviour of PMMA is weakly . structure in aeronautics, nuclear industry, and machinery equipment, against shocks or ballistic .. Elastic modulus and yield strain are almost identical, which.

In most rock-drilling models the value of the unconfined compressive strength of the rock (UCS) is used in the predictive equations, within the concept of . Other authors4-5 proposed to use additional rock properties besides UCS as parameters of drillability, such as tensile strength, modulus of elasticity, stiffness of the rock,.
