An approach to digital images correlation for measurements of masonry specimens in laboratory
Abstract
The aim of the work is to employ the Digital Image Correlation (DIC) technique to analyze displacements in masonry wallettes under axial compression, without using commercial software. An algorithm was developed using the Newton Raphson numerical method for this purpose. The results obtained were compared with measurements from the Linear Variable Differential Transformer (LVDT), validating the effectiveness of the algorithm and comparing them with previous studies, with acceptable errors. This work is part of an ongoing project at the Civil Engineering Institute of the Autonomous University of Nuevo León, laying the groundwork for future research on the implementation of the technique for obtaining pathologies and deformation states in masonry structures.
