modulus of elasticity
noun
, Physics.
- any of several coefficients of elasticity of a body, expressing the ratio between a stress or force per unit area that acts to deform the body and the corresponding fractional deformation caused by the stress.

modulus of elasticity
- 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.
- ◆ The ratio of the longitudinal strain to the longitudinal stress is called Young's modulus.
- ◆ The ratio of the stress on the body to the body's fractional decrease in volume is the bulk modulus.
- ◆ The ratio of the tangential force per unit area to the angular deformation in radians is the shear modulus.
