Webinar abstract

Digital image correlation (DIC) has become an important tool in material testing practices for the advanced characterization of materials in a wide range of applications. Despite that, the cost of a commercial 3D DIC system might still be a hurdle for many educational institutions, and even for some industrial establishments! 2D DIC is simple, inexpensive, and easily attainable, yet it lacks the accuracy and depth of field capabilities of 3D DIC. Despite this limitation, there are many testing scenarios where material deformation is planar and thus 2D DIC can capture material deformation with sufficient accuracy. This webinar aims to address this important issue by presenting direct technical comparisons between 2D and 3D DIC measurements for selected material testing scenarios. The ultimate goal is to enable those with limited access to 3D DIC to still take advantage of 2D DIC and capitalize on the benefits it brings in enriching investigations of material deformation & failure.
