Young's modulus is a mechanical property that measures the stiffness of the materials when force or compression is applied. Young's modulus relates to the elasticity of the material, which is ...

The elastic modulus relates the applied stress to the strain it produces. In a material that obeys Hooke's Law, the initial uniaxial elastic response is linear with stress and strain coupled through ...

In hard disk drives, digital information is stored and retrieved magnetically by a “read head” that flies over the disk within tens of nanometers of its surface. Figure 1 is a photograph of a read ...

In 1807, Thomas Young discovered that stress in a material (F/A) is linearly proportional to the strain (change in length/original length) in that material. This, in turn, led to the discovery of a ...

When a material experiences an applied uniaxial tensile stress, s, it displays a strain response, e. In the initial stage of strain, the response is linear in the stress and may be described by ...
