This research presents a uniaxial static stress estimation method for concrete structures by using digital image correlation (DIC) and finite element method. DIC is employed to measure the displacement field, which is induced by drilling a small hole on the concrete surface. The initial static stress level can be estimated by comparing the measured displacement field to that from the corresponding finite element model. A series of experiments in the laboratory environment is conducted to validate the proposed method.
