modulus of elasticity

[′mäj·ə·ləs əv i‚las′tis·əd·ē]
(mechanics)
The ratio of the increment of some specified form of stress to the increment of some specified form of strain, such as Young's modulus, the bulk modulus, or the shear modulus. Also known as coefficient of elasticity; elasticity modulus; elastic modulus.

modulus of elasticity

In an elastic material which has been subject to strain below its elastic limit, the ratio of the unit stress to the corresponding unit strain.
