Abstract:To achieve non-contact in situ detection of stress intensity factors (SIF), this paper innovatively adopts the advanced IRT and DIC synchronous detecting system to measure SIFs as using plastic zone range to assist in determining the state of stress fields. Though this synchronous detecting method has been applied to analyze thermomechanical coupling effects of materials, it has never been used to detect SIFs, which requires a high accuracy of point stress state detection. Thus, to testify its feasibility and … Show more
