The Guinan-Steinberg (GS) formula for the shear modulus at all pressures is widely used in material strength studies. 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 ...

The meaning of SHEAR MODULUS is the ratio of the shearing stress in a body to the corresponding shearing strain.
Where μ is the shear modulus of the unstressed rock (with an isotropic distribution of cracks), Pc is a characteristic crack closing pressure, σ0 is normal stress, and B=BN/BT is the ratio of normal to tangential compliances of individual cracks. ...
