The so-called Brazilian test or cylinder-splitting test is a common method for estimating the tensile strength of cement-based materials. The tensile strength at failure is calculated using the theory of elasticity and ignoring the effect of multiaxial state of stress. However, the state of stress is not uniaxial and there is likely to be redistribution of stresses due to nonlinearity. Cylindrical disk mortar specimens were tested and analyzed using laser holographic interferometry to verify the validity of obtaining the uniaxial tensile strength from the Brazilian test. Tests were conducted on a closed-loop control system to obtain stable crack propagation. Three-dimensional displacement fields were ascertained using a three-dimensional holographic setup and a computerized image analysis system. The holographically measured strain fields were compared with the numerical solutions based on linear elastic fracture mechanics (LEFM).
