| Abstract Scope |
We present a multimodal analysis of incipient polycrystalline plasticity from a titanium tensile sample. The dataset was generated from experimental acquisitions involving synchrotron DCT and conventional EBSD at the initial and deformed state. The DCT allows to generate a 3D digital twin (1 cubic mm) on which a full field FFT simulation was performed with a finite strain continuum crystal plasticity formalism. Following a careful registration of the modalities, a detailed comparison was performed at the mesoscopic, intergranular and intragranular (1 cubic µm voxel resolution) scales. Results demonstrated the higher performance of DCT over EBSD to track orientations while revealing in bulk new sub-grains mechanisms from the computation of GND fields. In addition the numerical results show good agreement with experiment at every scale while offering extra information to interpret the link between disorientation fields and plastic slip activity. |
