The effect of DIC parameters in the measurement of stress intensity factors Kı and Kıı / Lenny Iryani … [et al.]

In the present work, the effect of several Digital Image Correlation (DIC) parameters to the accuracy of the Stress Intensity Factors (K), was investigated. The values of Kı and Kıı were estimated in a three point bend specimen from the displacement field values around the crack tip obtained experim...
