Abstract

The results of the three-point bending test of the Brenna sandstone beam samples are presented. The values of strains at the peak strength of the tensile part was ϵ_xmax, the strength of three-point bending was σ_b and the modulus of longitudinal elasticity (of the tensile part) was E_b- A ll of these values were indicated. The values of constants obtained in the three-point bending tests were compared with those obtained in the uniaxial tensile and compressive tests and the Brazilian tests. For this typical sandstone, values of constants determined by the three-point bending tests are greater than those determined by the direct tensile tests. There were stated large differences in the tensile strength values (σ_b/σ_T3) and relatively small differences in the elasticity modulus E (E_b/E_T 1.2).
