The objective of GISTEAMMM is to characterize the grain structure generated by laser powder bed fusion (L-PBF) process at track scale: one track or single wall with several tracks, in which the grain structures will be obtained by both experiment and thermo-metallurgical-mechanical modelling. The anisotropic elastic-viscoplastic material laws at grain levels are expected to be extracted by considering the influence of inherent residual stress generated during printing process.
