These results show displacement and strain fields for the "weld" sample from SEM's DIC Challenge. This image set is a good way to demonstrate the abilities of Ncorr to analyze high strain. The parameters used were:

• Image Resolution: 1040x1392
• Analysis Type: regular
• RG-DIC Radius: 35
• Strain Radius: 7
• Subset Spacing: 3
• Diffnorm Cutoff: 1e-06
• Iteration Cutoff: 50
• Step Analysis: Seed Propagation
• RG-DIC Subset Truncation: Disabled
• Strain Subset Truncation: Disabled

The Lagrangian displacement fields for the last image in the set (with a postfix of 910) are shown below. The missing datapoints near the mid right section arise because a crack forms in this region.

For the strains, animations for the Eulerian-Almansi strain tensor are shown below (click them for a larger view):
