Theoretical shear strength of metal range in _______

Theoretical shear strength of metal range in _______ Correct Answer GPa

The shear modulus for metals is in the range of 20 to 150 GPa. Eq. τm=G/2π; predicts that the theoretical shear stress will be in the range (3 to 30 GPa), while actual values of the shear stress required to produce plastic deformation in single metal crystals are in the range 0.5 to 10 MPa. This large difference in values is due to defects and dislocation present in real crystals.
