抄録

The forms of the elastic-plastic boundary were described in the 1st report which concerns with the elastic-plastic torsion of a shaft with six semi-circular longitudinal grooves. Within the author's knowledge, for the shaft with complicated contour such as in the report, the warping of the cross-section has not yet been determined except the egg-shaped contour shaft. In this 2nd report the warping of the cross-section of the shaft is calculated on the basis of the results obtained in the 1st report. First, to determine the warping z in the elastic region, the relation between the value of z at each nodal point and the value of φ obtained in the 1st report is determined by placing the triangular net over the cross-section as in the 1st report; the value of z are obtained by relaxational method. After the warping in the elastic region is determined, the warping is the plastic region can easily be computed by the equation already established analytically.
