Interaction of Cyclic Torsion with Axial Loads

Source

The continuum mechanical theory of second-order strain accumulation and the theory of interaction of second-order extension due to cyclic torsion and sustained tension is summarized. The predicted linear interaction of second-order extension due to cyclic torsion and sustained tension is proved by experiments on superpure aluminum, copper, Armco iron, and 70-30 brass. It has been found that the conditions for interaction between cyclic torsion and axial stress are that the torsion angle be larger than the fatigue limit and the applied tensile stress be larger than the Bauschinger yield limit in tension produced by reversed cyclic torsion.
