The plastic yielding of double notched bars due to pure bending

It is believed that all practical cases of notch shapes are covered by the above analysis. The experiments are in favour of the upper bound solution, though, for practical cases, the mean value derived from the limit analysis differs very little from that of the bounds, and it can be used with confidence.
Further tests, however, are needed to confirm the deformation pattern. It is also believed that this analysis will furnish useful informations on the study on the mechanism of fracture.
