Abstract: Cracks induced by external excitation on a material that has defects may generate the stress concentration phenomenon. In the present project DIC technique is applied to the concrete member to measure surface displacements and strains. The technique is associated with the matlab programming in image processing. The measurement of the width of the localized zone on the surface of notched concrete beams under quasi-static three point bending helps in designing the structural components with high and low reinforcements as per the requirement thus providing safety for the structure and provides feasibility in designing slender sections. From the above experiment it is possible to define the zone where maximum strains are localized and consequently evaluate the flexural response of reinforced concrete beam and its size dependence. Thus the project helps in designing structures which satisfies serviceability, sustainability and durability conditions.
