摘要：

In this study, strain of fiber reinforced composites exhibiting multiple cracking under tensile load was compared by using traditional deformation meter (LVDT-Linear Variable Differential Transformer) and digital image correlation (DIC) method. In the DIC method, analyzes were performed by taking the influence of light (presence of controlled illumination), image resolution, subset size and step size parameters and two different methods of correlation into account. If appropriate subset size is selected, the strain values obtained by DIC analysis corresponded to the values obtained from LVDTs when images are taken under controlled lighting and high resolution conditions.
