Surface strainNumerical simulationImage process analysisCorrection of the stress-strain curve in the strained specimens after necking is one of the remarkable issues in mechanical engineering. The corrected curve strain-stress is needed to perform plastic or post-necking analysis in metals' large ...
This is interpreted to mean that the yield of the copper is gradual, and that during stage II of the stress-strain curve of the composites an appreciable portion of the copper continues to deform elastically.doi:10.1080/14786436908228703
strain. The stress at the point of intersection with the σ e − e curve is the offset yield stress. Figure 3 shows the engineering stress-strain curve for copper with an enlarged scale, now showing strains from zero up to specimen fracture. Here it appears that the rate of strain...
When a ductile material, such as copper or aluminum, is put under stress, initially, the resulting strain is proportional to the magnitude of the forces. This is depicted by the straight-line OA. The straight-line implies that stress and strain share a linear or direct relationship throughout...
However, beyond this point a neck forms where the local cross-sectional area decreases more quickly than the rest of the sample resulting in an increase in the true stress. On an engineering stress-strain curve this is seen as a decrease in the stress. Conversely, if the curve is plotted ...

The meaning of STRESS-STRAIN CURVE is a chart or curve showing the relation between the load or stress on a structural member or specimen of material and the corresponding strain or deformation.
