the stress distributions in the plane of fracture; considering plastic zone; dependency of ao/w on elastic rotational factor; range 0.15 <= ao/w <= 0.70,
Part I dealt with the evaluation of rotational factor considering the bending moment approach
arising out of the stress distributions in the plane of fracture in a notched 3PB specimen. Part II is an extension of a similar approach for the situation with a sharp crack. The rotational factor is found to be around 0.41-0.42 in elastic situation (without considering plastic zone) and varies between 0.42 and 0.47 in elastic-plastic situation (considering plastic zone). Effects of other variables like initial crack size (ao), load (P), elastic stress distribution range, state of stress, etc. have also been investigated. A mild dependency of ao/w on elastic rotational factor (re) is observed in the range 0.15 <= ao/w <= 0.70, while the
same is found to be independent of loading.
