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 ...

Oscillation Amplitude Sweep The oscillatory stress or strain is increased in this method, and the resulting changes in the elastic modulus (G') or the elastic stress (σ') due to increasing amplitude ...

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 ...

Many complex fluids, such as surfactant mesophases, network forming polymers, emulsions etc. do not flow until the applied stress crosses a certain critical value, called the yield stress. Materials ...

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 ...
