Direct Residual Stress Identification during Machining

“…For Global DIC (GDIC), a large RoI and a more elaborated set are chosen. To mention only a few, typical used shape functions are Chebyshev polynomials, Finite Element functions or NURBS [23]. In this paper, the chosen RoI matches the ZoI, which corresponds to the entire beam surface monitored with the camera.…”

Uncertainty of the virtual image correlation method

“…The applications of the VIC are possible in metrology and mechanical measurement, alone or in combination with the DIC. 10 Now that other authors are doing research around the VIC, 9,15 it will be time to study the advantages and disadvantages of the different proposals.…”

“…In a recent publication, 15 the authors propose a mechanical shape correlation (MSC) method that has similarities with the VIC. The correlation is done between a physical image and a virtual image obtained by FEM simulation and the correlation parameters are also the parameters of the mechanical model.…”

Adjusting fictitious domain parameters for fairly priced image-based modeling: Application to the regularization of Digital Image Correlation

“…Therefore our approach, consisting in exploiting the sample-specific model and the image gradient information contained in the domain boundaries by a DIC-type metric, appears as a promising strategy to investigate the mechanics of structured materials at their micro-structural scale. To some extent, our strategy shares many similarities with the newly-introduced mechanical shape correlation [89], although the latter requires greater confidence in the mechanical model.…”
