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 ...

Hysteresis is a measure of the amount of energy lost per cycle during deformation of an elastomer. Tangent delta, or the loss factor, is a measure of hysteresis and is the ratio of the loss modulus to ...

Typical nanomechanical applications include measuring elastic modulus, friction and adhesion. Viscoelastic materials, which include polymers and biological materials, have elastic properties that ...

This file type includes high resolution graphics and schematics when applicable. However, this relationship between stress and strain in a material is linear only when the force applied is within ...

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 ...
