Impact of Speckle Deformability on Digital Image Correlation

The Impact of Speckle Deformability on Digital Image Correlation (DIC) addresses the hazardous effects caused by the changes of speckle on the surface of any object measured using DIC, which undermines most of the prejudice with regards to displacements and strain calculations. Such factors range from types of materials undergoing deformation, deformation rates themselvesand to the imaging conditions applied.This topic allows to gain an understanding of the basic concepts of DIC and speckle pattern analysis as well as the normalization of measurement accuracy loss caused by speckle deformation. Advanced DIC techniques, such as multiscale, adaptive subset size, 3D, and dynamic DIC, are presented as solutions to overcome speckle deformabilitylimitations. Those working, studying or researching such areas as materials engineering, mechanical engineering, biomechanics, aerospace, automotive and biomedical is encouraged in this field. The aim is also to promote dialogue on the strategies of reducing risk factors and the successful application of techniques, as well as on the scope of research which should follow regarding a continued improvement of DIC measurements. This will enable the scientific community concerned DIC measurements of various materials to achieve higher resolution and minimized errors in DIC measurement techniques.
