Simulation of the Energy Balance in Metals under Irreversible Deformation

Abstract:

This work is devoted to the development of a constitutive model for the simulation of dissipated and stored energy evolutions under irreversible (plastic) deformation of metals. The efficiency of the model was demonstrated by the calculation of the energy balance in 304(L) austenitic steel under quasistatic deformation. The results of the numerical simulation are in a good agreement with the experimental data. The additional theoretical result of the study has established (based on the numerical and experimental data) a correlation between energy storage rate and rate of strain hardening.
