The tensile strength of the rock mass is estimated by Hoek and Brown (1997) to be (2)\[\sigma_{tm}\ =\ {\sigma_{ci} \over 2} \biggl(m_{b} - \sqrt{m^{2}_{b} + 4s}\biggr)\] Three properties are required in order to use the Hoek-Brown criteria (Equations (1) and (...

Material composition plays a crucial role in determining values. Different elements and their proportions can significantly affect the mechanical properties of a material, including its yield strength. For example, increasing the amount of carbon in certain materials can enhance tensile strength at yield...
In simpler terms, a material with high impact strength can be dropped on the floor without breaking. When looking at material properties, toughness is defined by the area under the stress-strain curve. “Toughness” or impact strength isn’t synonymous with stiffness, but it requires a balance...
This section is divided into four sub-sections. In this first sub-section, the case study and the information on the materials, their properties, and the weights of the criteria for the evaluation of the materials are represented. In the second section, a group decision-making process conducted...
