Crack front rotation and segmentation in mixed mode I+II or I+II+III. Part II: Comparison with experiments

摘要

Using the results presented in Part I, together with various criteria, we try to explain qual- itatiely and quantitatively crack front rotation and segmentation under mixed mode I+III or I+II+III conditions. We first give a qualitative explanation of segmentation in mode I+III, Based on the energetic theory of fracture. However, a satisfactory quantitative interpretation Would require knowledge of a parameter which theory is unable to predict and which is not Provided in experimental reports.
