| Abstract Scope |
A comprehensive workflow for generating realistic digital twins of microstructures using laboratory diffraction contrast tomography is presented to simulate and understand deformation mechanisms in pure titanium. The 3D microstructural information was acquired before deformation, leading to direct correspondence between the digital twin and the actual microstructure. A dislocation-based crystal plasticity model was employed to simulate the mechanical behavior of the polycrystal, incorporating slip transfer and blocking mechanisms. The simulated mechanical response was compared to experimental results obtained through high-resolution digital image correlation at various strain levels, which provided detailed information on the heterogeneous strain distribution after plastic deformation. This integrated experimental and simulation approach offers a realistic representation of microstructural behavior and provides new insights into the underlying physics of plastic deformation. The methodology demonstrates the potential of combining advanced characterization techniques with robust simulation models to enhance the understanding of deformation mechanisms in structural materials. |
