摘要：
The non-collinear mixing method for detection of plastic zone at crack tip is studied in this paper. When stress loaded on crack in solid is more than critical stress, which is related to length of crack, the crack will happen to expend fast leading to material fracture. However, critical stress of crack is affected by plastic zone existence at crack tip, so detection of plastic zone at crack tip is significant. By non-collinear mixing method, a nonlinearity parameter is utilized to evaluate plastic zone at crack tip. This paper demonstrates feasibility of non-collinear mixing method for measuring range of plastic zone at crack tip.
