Indirect Tension (Brazilian) Test
The Brazilian Test is a widely used laboratory technique in rock mechanics to estimate the tensile strength of rock samples indirectly.
Our Indirect Tension (Brazilian) Test Module can be integrated with any of our unconfined compression, triaxial, or point load frames, enabling the measurement of indirect tensile strength in rocks using the Brazilian Test method. This device is fully compliant with the standards outlined by the International Society for Rock Mechanics (ISRM).
In the Brazilian test, the rock specimen is loaded by two disparate normal strip loads on the disc periphery. Rock sample size has to be at least 54 mm (NX core size sample), or more than 10 times that of the average grain size. The ratio of the thickness/diameter should be 0.5 to 0.6. By increasing the load with a constant speed rate of 10 to 50 kN/min, the rock indirect tensile strength can be measured by the diametral compression of a disk.
