STRENGTH PROPERTIES OF ROCKS AND ROCK MASSES

In mechanics, compression is the application of balanced inward ("pushing") forces to different points on a material or structure, that is, forces with no net sum or torque directed so as to reduce its size in one or more directions. It is contrasted with tension or traction, the application of balanced outward ("pulling") forces; and with shearing forces, directed so as to displace layers of the material parallel to each other. The compressive strength of materials and structures is an important engi… WebThe unconfined compressive strength (q u) is the load per unit area at which the cylindrical specimen of a cohesive soil falls in compression. q u = P/A.

What is Flexural Strength and Why is it Important?

WebImportance of Flexural Strength. Calculation of flexural strength is considered crucial in structural mechanics. It helps in designing structural elements like beams, cantilevers, shafts, etc. Aids in the study of materials and their properties. Provides a parameter for development of stronger constructional materials. In mechanics, compressive strength (or compression strength) is the capacity of a material or structure to withstand loads tending to reduce size (as opposed to tensile strength which withstands loads tending to elongate). In other words, compressive strength resists compression (being pushed … See more When a specimen of material is loaded in such a way that it extends it is said to be in tension.
