Young's modulus

noun

, Physics.

1. a coefficient of elasticity of a substance, expressing the ratio between a stress that acts to change the length of a body and the fractional change in length caused by this force.

Young's modulus

noun

1. a modulus of elasticity, applicable to the stretching of a wire etc, equal to the ratio of the applied load per unit area of cross section to the increase in length per unit length E

Example Sentences

By measuring lattice distortion as a function of applied stress, the team found that when Sr2RuO4 is compressed by about 0.5%, a measure of mechanical stiffness known as the Young's modulus decreases by about 10%, and then increases by about 20% when the material is compressed further.

From Science Daily

“If you’re a structural engineer, you need to know about concrete steel reinforcing bars, things like Young’s modulus, stress, strain and so on.”

From Nature

A property called Young's modulus, which is an indicator of stiffness, was greater than that of some metals, and on its way to values associated with steel.

From BBC

It is not usual now to express Young's modulus of elasticity in terms of a length of the substance considered.

From Project Gutenberg

Young's modulus is employed in the cases of stretching and bending.
