The shear modulus $G$ gives information about the linear-elastic material behavior. How does it behave in the area of plastic deformation? With $ \tau=G\tan\gamma$, shear modulus should get smaller up to a limit value (break), right? I am thinking of metal with plastic strains up to 5%.

Shear modulus with plastic deformation

The shear modulus G gives information about the linear-elastic material behavior. How does it behave in the area of plastic deformation? With $ \tau=G*tan(\gamma) $ shear modulus should get smaller up to a limit value (break), right?
