n: see modulus of elasticity .

n: the point at which a material permanently deforms when stressed.

n: the maximum stress standed by material keeping elastic deformation without perpetual deformation

the upper range of elasticity, just before the body is permanently deformed.

n: see modulus of elasticity,

the tendency of a body to return to its original shape and size once the stress is removed.

n: see modulus of elasticity.

n: the ratio of the increment of some specified form of stress to the increment of some specified form of strain, such as bulk modulus, shear modulus, or Youngs modulus. Also called coefficient of elasticity. elasticity modulus, elastic modulus.

stress over strain. A measure of stiffness or Young’s Modulus (E). Rocks are ½ to 12 x 106 psi and mild steel is 30 x 106 psi. Modulus refers to stress at a predetermined level of elongation, usually at 100% elongation. The higher the modulus of a compoun

n: the steel brush-shape scraper with high elasticity,installed on the casing string and going up and down along with the casing string to scrape mud cake during casing installation

n: a coefficient of elasticity that expresses the ratio of the force per unit area that deforms the substance laterally and the shear produced by this force.
