Local investigations of the thermomecanical behavior of a coarse-grained aluminium multicrystal using constrained DIC and IRT methods

Abstract : With the intention of achieving grain scale energy balances at finite strain, a mechanical test on a coarse-grained aluminium is presented in this paper using two complementary imaging techniques (visible and infrared). Specific image processing methods (Constrained DIC and Constrained IRT) are applied to investigate the thermomechanical behavior at the microstructural scale. In the long term, the ultimate goal is to provide energy balance during mechanically-loaded test at the granular scale in order to propose thermomechanically consistent constitutive modelling of crystalline plasticity.
