Micromechanical modelling was widely developed during the past 20 years as they enable ones to make direct links between the actual microstructure of a material and its macroscopic properties such as mechanical, thermal, electrical, etc. Crystal plasticity models aim at predicting local and macroscopic behaviours and/or changes of the microstructure during thermomechanical loading. However, the parameters of these models are difficult to identify, because the mechanisms they describe are at a small scale and are thus complicated to measure. For this reason, the crystalline model identification requires the use of experimental data at the grain scale. The objective of the study presented here is to develop a robust procedure to obtain at lea...
