Elastic Modulus 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 ...

These are nonlinear elastic materials for which the slope of the stress-strain curve, (d s /d e) e, is the strain dependent elastic modulus, the Tangent modulus. Elastic deformation continues until ...

The imaginary part (e.g., tensile loss modulus, E”) illustrates the viscous or out-of-phase part of the response and is given by (stress/strain)*sinδ. The ratio between loss modulus and storage ...
