Abstract

In the case of cyclic plasticity, the validity of a constitutive model is usually assessed using stress-strain curves. However, this description can be enriched by adopting an energetic point of view. Thus, in the present work, a multiscale model is developed to estimate the amount of energy which is either dissipated into heat or stored in the material in a medium carbon steel under cyclic loading. The results emphasize the heterogeneous aspect of the stored and dissipated energy fields at a microscopic scale.
