The use of stress and strain differences taken at the end of a small pause introduced at each reversal eliminated the dual nature of the curve. It is proposed that the use of a random cyclic strain sequence with a pause at each reversal would provide an alternative method of measuring ...

aIt should be noted that material cyclic stress-strain curves should be used instead of the monotonic loading curve; in this work due to relatively low metal temperature (108°C maximum) and limited cycles due to dominantly steady state operation of unit (startup and shutdowns only) the monot...
This chapter is mainly concerned with the specification of stress-strain relationships under monotonic and cyclic loading. Various factors such as rate of loading, environment and temperature affect the stress-strain relationship. It will be seen that the cyclic stress-strain curve differs from that ...
The cyclic stress-strain curve of single-slip-oriented single crystals of low-stacking-fault-energy alloy Cu-22%Zn was determined on a large number of specimens. There was an expressive plateau extending from a plastic shear strain amplitude of about 7 × 10 −4 to about 7 × 10 −3 ...

The cyclic stress-strain curve associated with the large step test followed that observed in constant plastic strain testing (see Part I, the companion paper to this) with some differences at low strain. The cyclic stress-strain curve associated with the small step test followed that observed in...
