CONDITIONS FOR INTERACTION OF CYCLIC TORSION WITH AXIAL LOADS.

Abstract

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 (elastic limit) and the applied tensile stress be larger than the Bauschinger yield limit in tension produced by reversed cyclic torsion.
