The development of the Brazilian disc test for determining indirect tensile strength and its applications in rock mechanics are reviewed herein. Based on the history of research on the Brazilian test by analytical, experimental, and numerical approaches, three research stages can be identified. Most of the early studies focused on the tensile stress distribution in Brazilian disc specimens, while ignoring the tensile strain distribution. The observation of different crack initiation positions… 
The Brazilian splitting test is commonly used in order to estimate the tensile strength of brittle materials such as rocks and concretes. This test is performed by compressing a specimen disc in the
Evaluation on Rock Tensile Failure of the Brazilian Discs under Different Loading Configurations by Digital Image Correlation
The fracture behavior of the disc specimens in the Brazilian test is closely related to the reliability and accuracy of the experimental results. To comprehensively investigate the effect of various
Modified Formula for the Tensile Strength as Obtained by the Flattened Brazilian Disk Test
Tensile strength, one of the basic mechanical parameters for rocks and rock-like materials, is generally determined through direct and indirect testing methods. The Brazilian test, a typical indirect
Effects of Micro-structure and Micro-parameters on Brazilian Tensile Strength Using Flat-Joint Model
Abstract It has been widely accepted that tensile strength plays a dominant role in the failure mechanism of rock or rock-like material. Tensile strength is determined mainly via two methods: the
Numerical Simulation of the Effect of Loading Angle on Initial Cracks Position Point: Application to the Brazilian Test
The Brazilian Test is the most used test to determine the indirect tensile strength for brittle materials like concrete. It has been observed that the success of the test depends on the cracks
Evaluation of tensile strength of Brazilian test under solid and ring disks using finite element analysis
The tensile strength of intact rock materials has been determined by indirect method more frequent than the direct method. The most commonly used indirect method is Brazilian test. Stress and


Experimental, numerical and analytical studies on tensile strength of rocks
Experimental and Numerical Studies on Determination of Indirect Tensile Strength of Rocks
Indirect tension tests using Brisbane tuff Brazilian disc specimens under standard Brazilian jaws and various loading arcs were performed. The standard Brazilian indirect tensile tests caused
Brazilian test : stress field and tensile strength of anisotropic rocks using an analytical solution
Tensile strength of rock is among the most important parameters influencing rock deformability, rock crushing and blasting results. To calculate the tensile strength from the indirect tensile
Investigating the Effect of Cyclic Loading on the Indirect Tensile Strength of Rocks
This paper presents the results of laboratory experiments during the investigation of the stress–strain characteristics of Brisbane tuff disc specimens under diametral compressive cyclic loading. Two
3-D distribution of tensile stress in rock specimens for the Brazilian test
It is claimed that the formula used for calculating the tensile strength of a disk-shaped rock specimen in the Brazilian test is not accurate, because the formula is based on the 2-dimensional
The extensively used formula for estimating the tensile strength of rocks under the Brazilian test is based on the 2D elastic theory and only suitable for very long or very short cylinders.
Position and load of failure in Brazilian test; A numerical analysis by Griffith criterion.
Failure in the Brazilian test (diametral compression of a disc) has been numerically analyzed on the basis of the Griffith fracture criterion. The analysis indicates that the angle subtended by the
Size effect and boundary conditions in the brazilian test: theoretical analysis
Splitting strength determined in the Brazilian test is assumed to be a property independent of size and uniquely related to the intrinsic material strength. However, as was experimentally
