exist that attempt to predict the shear modulus of metals (and possibly that of alloys). Shear modulus models that have been used in plastic flow computations include:

# the Varshni-Chen-Gray model developed by Y. P. Varshni and used in conjunction with the mechanical threshold stress (MTS) plastic flow stress model.
# the Steinberg-Cochran-Guinan (SCG) shear modulus model developed by M. W. Guinan and D. J. Steinberg and used in conjunction with the Steinberg-Cochran-Guinan-Lund
