8. STRENGTH OF SOILS AND ROCKS
people.eng.unimelb.edu.auThe tensile strength of soil is very low or negligible and in most analyses it is considered to be zero. 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.
