000015478 520__ $$2eng$$aIn this work, we use a multiscale modelling approach to understand the role of lattice strain evolution during biaxial loading of cruciform shaped samples of 316L steel. Finite element simulations performed on cruciform samples provide correct macroscopic boundary conditions to drive the meso-scale elasto-viscoplastic fast Fourier transform model. Lattice strains are predicted along one of the principal directions of the cruciform sample and compared with in-situ neutron diffraction experiments. Results show that at the macroscopic scale uniaxial load on cruciform sample results in biaxial stress state in the gauge area. This contributes to kinks observed in lattice strain evolution from diffraction peaks. During equibiaxial loading the spread in lattice strain evolution is much lower than in uniaxial loading. This implies that elastic anisotropy of 316L steel does not play a significant role in lattice strain evolution in the in-plane direction during equibiaxial loading.
