This paper presents the application of Digital Image Correlation (DIC) to measure displacements and detect crack pattern in tensile and bond tests on Textile Reinforced Mortar (TRM) composites. DIC is a full-field contactless optical method based on the correlation of the digital images taken during test execution. With respect to conventional methods, it offers the advantageous possibility of selecting several measurement points after the test, is more cost-efficient, does not entail any risks of damage to instrumentation, and is generally less affected by stroke or encumbrance limitations. On the other hand, it detects only the outer surface of the specimen and requires particular care for setup preparation. In this work, two DIC software programs were used and their results were compared to each other as well as to those provided by traditional transducers for mutual validation. The advantages offered by DIC as a tool for improving the mechanical characterization of TRMs and for developing a deeper understanding of their behaviour are discussed together with some of its limitations.
