Abstract :In this study, the effect of image resolution on the determination of mechanical parameters and multiple crack properties of Engineered Cementitious Composites insert ignore into journalissuearticles values(ECC); was investigated by digital image correlation insert ignore into journalissuearticles values(DIC);. For this purpose, low and high resolution images were captured during the tensile loading of ECC by using two cameras simultaneously. DIC analyzes were performed on the images and results were compared both within themselves and with the traditional method. Mechanical parameters have been successfully calculated with DIC analysis and consistent values obtained with traditional methodology. However, high resolution images were found to be more effective for detecting pattern properties than low resolution images. It resulted in low strain error when using high resolution images compared to low resolution images in DIC analysis. Finally, when the high resolution images were used in DIC analysis as opposed to the low resolution images, both the detected number of cracks and calculated crack widths were obtained accurately. This situation was proven by local strain maps provided by DIC.
