Shear Modulus, G
G or shear modulus is defined as the ratio of shear StressStress is defined as a level of force applied on a sample with a well-defined cross section. (Stress = force/area). Samples having a circular or rectangular cross section can be compressed or stretched. Elastic materials like rubber can be stretched up to 5 to 10 times their original length.stress and shear StrainStrain describes a deformation of a material, which is loaded mechanically by an external force or stress. Rubber compounds show creep properties, if a static load is applied.strain.

F is the acting force
A is the area on which the force is applied

Δx is the displacement of the body
L is the original length
*Txy is an “out-of-diagonal” component of the 3-dimensional shear tensor describing the active component of StressStress is defined as a level of force applied on a sample with a well-defined cross section.
