Through analyzing the causes of various welding accidents, we found that the major cause for damage imposed after welding parts are loaded is the fracture of materials. Therefore, studying the influence of welding residual stress on the fracture property of materials is of great significance. This paper applied the digital image correlation technique to study the fracture property of welding parts under the influence of welding residual stress. In addition, standard parts and welding parts were selected to carry out a contrast experiment. Room temperature tensile tests were performed on both standard parts and test pieces after residual stress measurement. Using displacement field and strain field data obtained through VIC-2D software, the stress intensity factor around the crack tip of each specimen under the conditions of small load was calculated and corresponding analysis was carried out.}, type={Artykuły / Articles}, title={Badania materiału pod kątem złamania z oderwania i przemieszczenia otworu szczeliny w oparciu o metodę cyfrowej korelacji obrazów}, title={Material test on strain fracture and crack opening displacement based on digital image correlation method}, URL={http://ochroma.man.poznan.pl/Content/84112/mainfile.pdf}, keywords={metoda cyfrowej korelacji obrazów, szczelina, złamanie, spawanie, Digital image correlation method, crack, fracture, welding}, }
