Research into nonlinear elasticity and dynamic acoustoelastic testing has advanced our understanding of how geomaterials respond under varying strain conditions. This field examines the deviation from ...

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 ...

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 ...
