As a measurement tool, Digital Image Correlation (DIC) is becoming an accepted technique in both industry and academia, as it allows full field, contact-less, 3D-measurement of deformations at the surface of any type of material and under arbitrary loading, combining ease-of-use with high flexibility. As MatchID’s tagline is “Metrology beyond colors”, we seek to offer the DIC system of the future, by adopting a module-based structure, where the focus lies primarily on the metrological aspects: - Optimal test setups and processing: patterns, experimental tools and automated post-processing - Interpretation of results in a quantitative way, focusing on resolution and spatial resolution, with integrated error assessment - Direct integration of external scripts and programs, independent of coding language - AppStore for sharing of knowledge throughout global MatchID community - Enabling direct, quantitative comparison to numerical models - Full-field stress reconstruction, well beyond standard elastic behavior - Direct identification of material properties through the Virtual Fields Method (VFM) - Customized application development - In-depth training: annual courses by experts in the field While the MatchID platform can be used simply as a measurement tool, it expands on this by seamlessly integrating virtual fields methodologies (VFM) which allow the direct identification of mechanical properties from the captured DIC images. This is done without the need for coupling to external FE software or time-consuming updating algorithms. In summary, MatchID can support all stages in the engineering process from determination of material properties towards extended model validation.
