Modulus of Elasticity of Rock Modulus of elasticity of rocks depend upon several factors, such as, Type of rock Porosity Grain size Water content Value of modulus of elasticity can be determined by static or dynamic methods. Higher value of modulus of elasticity indicates good quality rock having sound composition. Typical values of modulus of [.]

Basalt rock characteristics vary from the source of lava, cooling rate, and historical exposure to the elements. High quality fibers are made from basalt deposits with uniform chemical makeup. The production of basalt and glass fibers are similar. Crushed basalt rock is the only raw material required for manufacturing the fiber.

Rock - Rock - Stress-strain relationships: The deformation of materials is characterized by stress-strain relations. For elastic-behaviour materials, the strain is proportional to the load (i.e., the applied stress). The strain is immediate with stress and is reversible (recoverable) up to the yield point stress, beyond which permanent strain results.
