Abstract
Digital Image Correlation (DIC) is widely used in experimental mechanics for full field measurement of displacements and strains. The application of this technique, normally requires the preparation of specimens with a random speckle pattern, via spray painting, stamping,
manual patterning, etc. The applicability of most techniques to create random patterns is still limited. For instance, traditional methods such as airbrush painting are not suitable when time available to produce the speckle pattern is limited. The development and application of a novel
technique to address this problem is presented in this paper. The developed technique makes use of commercially available temporary tattoo paper, adhesives, and paint. The presented technique showed to be quick, repeatable, consistent, and stable even under impact loads and
large deformations. Additionally, they offer the possibility to optimise and customise the speckle pattern.
