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
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...
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.
Ductile Curve 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 relations...
此弹性区域的材料模数( 杨氏模数,弹性模数) 为一常数定值;所谓模数Modulus=(stress)/(strain) 即为应力-应变曲线上的对应斜率,在此弹性区域上可以藉由简单的应变量值与起始弹性模数的乘积,来计算出应力值,可作为产品设计上的参考依据。 图2: 塑胶材料的应力- 应变曲线图...
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...

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 hardening 2 diminishes up to a point labeled UTS, for Ultimate Tensile Strength (denoted σ f in these modules...
