Elasticity refers to the property of reversibility of deformation when subjected to a load. Many fresh, hard rocks are elastic when considered as laboratory specimens. But on the field scale rocks can be expected to contain fractures, fissures, bedding planes, contacts, zones of altered rock and clays with plastic properties. Therefore, most ...
where E is the Young''s Modulus and υis the Poisson''s ratio. Poisson''s ratio varies between and for rocks. A principal stress component σ i produces a strain σ I /E in the same direction and strains (υ.σ i / E) in orthogonal directions. Elastic behaviour of an isotropic material can be characterized
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.
Modulus of elasticity of concretes produced with basaltic aggregate basaltic aggregates;modulus of elasticity;commercial concrete;Eurocode 2; Basalt is a type of volcanic rocks, grey to black in colour, contains less than 20% quartz, 10% feldspathoid, and at least 65% of the feldspar of its volume. Basalt is considered an igneous rock with fine grains due to the rapid cooling of lava.
The large ranges emphasize the need for testing at each site.

Aug 15, 2015· Strength and Modulus of Weathered Rock from SPT Values. In the weathered rock it is difficult to drive the split sampler to the full specified depth as in soil. Hence we may estimate the strength and elastic modulus values of weathered rock by driving the spt apparatus for a fixed number of blows and find the penetration.
On comparing the properties of the rocks (Table 8 and Fig. 5) and their behaviours under compressive stress, the features that first attract attention are 1) very high values of compressive strength and elastic modulus of the basalt rock and 2) surprisingly low elastic modulus of the granite rock and very high compressive strain in the rock at ...
Young''s modulus, or the Young modulus, is a mechanical property that measures the stiffness of a solid material. It defines the relationship between stress (force per unit area) and strain (proportional deformation) in a material in the linear elasticity regime of a uniaxial deformation.. Young''s modulus is named after the 19thcentury British scientist Thomas Young.
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 [.]

2. ON DEFORMATION AND ELASTIC MODULI Definitions Deformability is characterized by a modulus describing the relationship between the applied load and the resulting strain. The fact that jointed rock masses do not behave elastically has prompted the usage of the term modulus of deformation rather than modulus of elasticity or Young''s modulus.
