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 ...
and this graph is referred to as the stress-strain curve, where stress is plotted on the Y-axis and strain is plotted on the X-axis. Although there are a plethora of materials at our disposal, we can essentially classify them into

emThe influence of stress- and strain-controlled loading on microstructure and cyclic plastic behaviour of ultrafine-grained copper prepared by equal channel angular pressing was examined. The stability of microstructure is a characteristic feature for stress-controlled test whereas grain coarsening and ...

neutron beamsThe influence of neutron irradiation, from dose levels of 10 1015 to 097 1019 nvt, on the strain rate dependence of the flow stress in copper single crystals has been investigated at 77°K and 300°K. An analysis of this dependence shows that the activation energy for ...
Residual strains were measured in the cold-sprayed copper parts by neutron diffraction. The neutron diffraction technique was required to measure strain inside the parts due to their thickness. Compared with synchrotron radia- tion for strain scanning (Ref 30), the neutron technique can reach ...
