A Study on the Optimal Stress Compensation to Dynamic Recrrystallization for the Estimation of Forming Loads
초록
The effect of dynamic recrystallization during hot forming process was implemented to a commercial FEM code by conditioned remeshing and remapping of sate variables. A datum strain for stress compensation was determined as a strain for maximum softening rate and was able to be formulated as a function of critical strain f(
