In contrast a number of direct or indirect tensile strength tests are commonly carried out for rock. In a direct tensile strength test a cylindrical rock specimen is stressed along its axis by means of a tensile force.Estimating compressive strength. General rock failure criterion can be reduced to a few parameters dependent on lithology (m) and the uniaxial compressive strength (C 0).Lithology is commonly derived during log analysis,
