Dissipative energy as an indicator of material microstructural evolution
Laboratoire de mécanique et procédés de fabrication (LMPF),
Arts et Metiers ParisTech, rue St Do minique, BP 508, 51006
In this study, the material microstructure evolution has been studied thanks to two indicators: the cumulated plastic strain and the energy dissipation due to internal friction under cyclic loading. An experimental procedure has been designed to underline the variations of the dissipative energy due to cold work on a DP600 specimen. The results showed that the dissipative energy increases with the plastic strain and can be used as an indicator of material microstructural evolution.
