Figure 8
Reconstructed strain field using WLSQ (left column) and the GP method (middle column) of a columnar tin grain embedded within a polycrystalline sample. The rightmost column depicts the estimated uncertainty of the GP reconstruction. The 3D surface of the voxelated grain is presented together with a pull-out enlarged interior spherical cut with its centre at the grain centroid and a radius of 1 µm. Two separate colormaps have been assigned to enhance contrast for the various fields. However, the units of strain remain the same across plots (×10−4). |
