Title:Creep torsion of SAE 1020 steel bars at elevated temperatures

Abstract:In two previous investigations (References 13 and 14) theories were presented for predicting the creep deformations of circular and non-circular cross-sections. In these investigations excellent agreement was found between theory and experiment for torsion made of homogeneous plastics. The present investigation was undertaken to compare the theories with data obtained from torsion members having circular, hollow circular, square, and rectangular cross-sections, made of SAE 1020 steel and tested at 975°F. (The hollow circular torsion members were not tested until after completing the original investigation and are not discussed until Section IV.) In general the theories were found to be conservative in predicting the deformation. The discrepancy between theory and experiment was not considered excessive since an increase in the torque by less than 10 percent would have produced deformations greater, in most cases, than that predicted by theory.
