Influence of specimen shape on the indirect tensile strength of transversely isotropic dionysos marble using the three-point bending test

This paper focuses on the investigation of the three-point bending tensile strength of Dionysos marble. Using the classical relationship obtained from the theory of elasticity, the effect of the span length, the thickness/width ratio and the orientation of the specimens in the indirect tensile strength were investigated. In total, 42 experiments were carried out, divided in three sets of specially designed beams. Finally, the calculated bending tensile strength is compared with the corresponding value obtained from Brazilian indirect tension as well as ring tests.
