Figure 3
Strain tensor reconstruction (REC) of a single-crystal α-quartz grain slice. The matrix factorization in equation (29) has been used to reconstruct the strain field without the need to assemble the global system matrix. The top row ground-truth simulation input (GT) is to be compared with the middle row reconstructed strain field (REC). The bottom row shows the residual between reconstructed and true strain fields (RES). |
