Abstract
The digital image correlation offers an alternative to the conventional measurement techniques, as it is simple to use and cost effective. The paper presents and analyses displacement and crack width results for reinforced concrete samples, obtained by means of the 2D digital image correlation and LVDT sensors. The equipment used for digital image correlation includes a plain digital camera, personal computer, and a free version of a commercial photo processing program. Laboratory static test results for three specimens are compared and the 2D digital image correlation method is validated.
