The Steinberg--Guinan--Lund rate-dependent constitutive model has been successfully applied to molybdenum [D. J. Steinberg and C. M. Lund, J. Appl. Phys. [bold 65], 1528 (1989)]. The model reproduces yield strength versus strain rate and temperature data and also successfully simulates rate-dependent phenomena, such as shock-smearing, precursor decay, and precursor on reshock, as observed in one-dimensional gas gun experiments. The spall strength of molybdenum was determined to be 1.5 GPa.
