摘要

•The complete stress-strain response of SLM Ti-6–4 was predicted by a CP-FE model.•Crack band theory was used to eliminate mesh-sensitivity of the model.•A statistically equivalent RVE was created from three orthogonal EBSD images.•The CP-FE model was validated against unseen experimental data.
