As we demonstrate here, the GS formula predicts a value for the shear modulus that is higher than its actual value at low to moderate compressions, even if it has the correct ultrahigh pressure limit. We show that the reason for this shortcoming is insufficient negative curvature in the GS ...
Elastic modulus is defined as the ratio of stress to strain below the proportional limit. It is a measurement of a material’s rigidity or stiffness. The slope of the stress-strain curve in the range of linear proportionality of stress to strain in terms of the stress-strain curve is the ...
2.12.2.1.3 Shear modulus23 The shear modulus at room temperature of 191 GPa for CVD SiC has been determined by the four-point bending technique. This value was also derived from the elastic modulus and Poisson’s ratio (ν), using the conventional formula for isotropic solids: G = E/2(...
We derive an exact formula for the volume fraction of an inclusion in a body when the inclusion and the body are linearly elastic materials with the same shear modulus. Our formula depends on an appropriate measurement of the displacement and traction around the boundary of the body. In ...

Given the Shear Modulus (G) of the material, the above formula can be used to calculate the value of F needed to displace the sheet. Since this was an infrastructure project, we assumed Δx to be 0.1mm (a very small displacement) and given the other properties, the force was calculated...
