| Summary: | 碩士 === 國立臺北科技大學 === 機械工程系機電整合碩士班 === 106 === In this paper. Fixing the DIC algorithm to overcome that DIC can’t track large deformation and using high-resolution image to measure displacement field and strain field of Standard specimen of ASTM B557M. The experiment result are consistent with strain gauge that express DIC has the ability to measure strain in tensile test. Combine DIC and MTS to get Stress-Strain curve, further get Youngs modulus of elasticity, Yielding Stress and Ultimate stress. Also Using Stereo DIC to measure True stress-strain of specimen.
