For the bars with initial deflection under tension loads at ends there are two cases to be treated separately according to the condition whether the compression side remains elastic all through the deformation or becomes plastic if it is only partial and temporary before the entire cross-section reaches the ultimate state of uniform tensile stress. The former case is treated in the previous report and in this paper the latter case is discussed. It is shown that in the course of deformation development there are seven stress distribution patterns, the sequence of which can be classified into three categoriesin accordance with the combination of initial deflection ratio and slenderness ratio.
