The ratio of the stress applied to a body to the strain that results in the body in response to it. The modulus of elasticity of a material is a measure of its stiffness and for most materials remains constant over a range of stress. &diamf3; The ratio of the longitudinal strain to the longitudinal stress is called Young's modulus. &diamf3; The ratio of the stress on the body to the body's fractional decrease in volume is the bulk modulus. &diamf3; The ratio of the tangential force per unit area to the angular deformation in radians is the shear modulus.
(physics) Young's modulus.
Modulus-of-elasticity Sentence Examples
But if y is the displacement at A, dy/dx is the extension at A, and the force acting is a pull across A equal to Y&uodyldx, where Y is Young's modulus of elasticity.
Owing to the yielding of joints when a beam is first loaded a smaller modulus of elasticity should be taken than for a solid bar.
Is this because cast gold has a higher, or lower, modulus of elasticity compared to cobalt chromium?
rhenium alloy that maintains a high modulus of elasticity even at high temperatures.
In portions of the structure liable to important changes of pressure from the rise, and fall of the water and subject to the additional stresses which expansion and contraction by changes of temperature and of moisture induce, and in view of the great difficulty of securing that the average modulus of elasticity in all parts of the structure shall be approximately the same, it is probably desirable to limit the calculated load upon any external work, even of the best kind, to 15 or 20 tons per sq.
