"Grain size dependence of modified material constitutive model for OFHC" by Tao Zhang, Lan Yan et al.
Grain refinement occurs during manufacturing process, and grain size has a significant impact on mechanical properties. It is essential to establish the relationship between grain evolution and plastic behavior. The quasi-static and dynamic compression experiments for three kinds of oxygen-free high-conductivity (OFHC) copper with different grain sizes have been carried out. The true stress-strain curves were corrected to the isothermal curves, in which the temperature dependence of the specific...
