Abstract

A strength of Digital Image Correlation (DIC) is the potential manoeuvrability of the system, so long as the material can be loaded in some way for analysis [1]. This produces an interesting problem regarding how to deform a component in the field rather than in the controlled lab environment. Parallel to this limitation, there is an issue of a dependency on user capabilities with both the setup of the test and coupon preparation. This investigation analysed the possibility of using a pre-speckled bag to encase and load multiple components of complex geometries, via the evacuation of internal air. Each coupon within the bag was either originally white in colour, or spray painted with a matt white acrylic paint. The reason for this was to increase contrast between the component and the black speckles upon the bag. Results suggested that using the speckled bag, the algorithm was confident of strain mapping accurately for subsets larger than 31 pixels and could plot strain profiles for geometrically complex objects.
