SECOND-ORDER ELONGATION OF METAL TUBES IN CYCLIC TORSION.

Abstract

Aluminum tubes of different wall-thickness are subjected to reversed cyclic torsion of the same amplitude superimposed on the same axial tensile stress. The observed strong dependence on wall thickness of the axial extension accumulating with the number of torsion cycles ('cyclic creep') implies that this phenomenon is due to the amplification, by superimposed tension, of accumulating second-order strain increments.
