Phenomenological representations of the stress-strain curve, which give good agreement with tensile test results for copper, are shown to be inadequate when a large strain range is considered. It should be noted, however that the large strain was developed by wire drawing and there is the possibi...
Tensile stress strain data for 99.999% copper at room and liquid nitrogen temperature as a function of grain size are presented together with some microstructural observations made by transmission electron microscopy. It is shown that the flow stress data, at constant strain may be expressed in term...
The stress-strain curve is a graphical measure of the strength and elasticity of a material. It is used to predict the behavior of materials used in a given application. The stress-strain graph provides engineers and designers a graphical measure of the strength and elasticity of a material. ...
The cyclic stress-strain response of polycrystalline copper has been explored at low strain amplitudes by means of two multistep tests. In one called the 'large step test', Program A, cycling is first begun at 2 × 10 3 to create a cell structure in saturation and thereafter tests were co...

Copper single crystals oriented for single slip were cyclically loaded under load control with a non-zero mean stress. Contrary to symmetrical strain controlled tests there is no plateau at the cyclic stress-strain plot and there are no persistent slip bands in the dislocation structure. The ...
The present study reports on the cyclic stress–strain response of ultrafine grained copper obtained by equal channel angular extrusion (ECAE). Fatigue behavior of material subjected to between 8 and 16 ECAE passes was studied both in constant amplitude and incremental step tests. Transmission electron...
