Displacement distribution in circular shaft specimen of steel during tensile test was measured using digital image correlation (DIC) method. Video image of the specimen surface was continuously taken during tensile test and static images were converted from the movie file after the test. Distributions of strains in axial and in vertical directions were obtained from the displacement distribution and also diameter of the specimen was estimated based on strain distribution in vertical direction to the specimen axis. Distributions of strain and diameter of the specimen were measured during whole tensile test and material properties were derived.
