A rate‐dependent constitutive model for molybdenum

摘要

The Steinberg–Guinan–Lund rate‐dependent constitutive model has been successfully applied to molybdenum D. J. Steinberg and C. M. Lund, J. Appl. Phys.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.
