摘要

This paper is based on additional treatments of the experimental results obtained by L. Bodelot, L. Sabatier, E. Charkaluk, P, Dufrenoy [Experimental setup for fully coupled kinematic and thermal measurements at the microstructure scale of an AISI 3161 steel, Mater. Sci. Eng. A 501 (2009) 52-60]. In order to perform inter- and intragranular thermomechanical analyses in a metallic polycrystal at the grain scale, a crystallography-based projection technique of the thermal and displacement fields on a polynomial basis is proposed. It enables intragranular coupled analysis of strain and temperature full-field data consistent with the plastic slip activation observed on specimen surface after the test.
