Abstract Scope The lattice strain and intensity evolution obtained from in-situ neutron diffraction experiments of 316L cruciform samples subjected to 45 and 90 load path changes are presented and predicted using a multi-scale modeling approach. At the macroscale, the multi-scale approach uses the implementation of the viscoplastic self-consistent polycrystalline model as a user-material into Abaqus FE framework to predict the non-linearly coupled gauge stresses of the cruciform geometry. The predicted gauge stresses are then used to drive the EVP-FFT polycrystalline model to predict the lattice strain and intensity evolutions. Both models use the same dislocation density based hardening law suitable for load path changes. The predicted lattice strain and intensity evolutions are compared with the experimental measurements for all reflections studied. Following validation, the simulation results are analyzed in detail to understand the role of elastic anisotropy, plastic slip and grain neighborhood interactions on the microstructural evolution during biaxial load path changes.
