The yielding phenomena of steel bar under uniform bending stress has been fully explained by the authors. The yielding phenomena of a twisted steel bar has also been discussed in the same manner. The idea is supported by their experiments for specimens of various sectional shapes of steel bars. But these are the cases where the stress gradient does not exist in the axial direction. In the present paper, the authors intend to examine whether their theory is applicable even when the stress gradient exists in the axial direction, e. g., the yielding of bending steel bar under concentrated load. The problems of elastic-plastic bending are treated analytically in the same manner as in the former cases and the result is compared with the experiments. The both results agreed very well, and it is ascertained that the theory is applicale to the present case.
