Stress-strain curveHigh-pressure torsionAluminumSuper large strain rangeAluminum alloyCarbon steelIn measurements of stress-strain (SS) curves, it is difficult to achieve a large strain, i.e., 5 (500%), which is introduced in actual metal forming processes. Recently, a constrained-type high-...
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.

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...

40 硬度 eva 压缩反力 stress strain curve 材料的压缩反力与应力-应变曲线(stress-strain curve)之间的关 系取决于材料的硬度、弹性模量等性质。EVA(乙烯-醋酸乙烯共聚物) 通常是一种弹性较好的材料,其应力-应变曲线可能表现为一个典型 的弹性区域,然后是一个流变区域。 在理想的弹性区域,应力(stress)与应变(...
Equations 1 and 3, the true-stress-true-strain curve always appears to the left of the engineering curve until maximum load is reached. However, beyond maximum load, the highly localized strains in the necked region used in Equation 4 far exceed the engineering strain calculated from Equation ...
