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.
显示为金属材料典型的应力- 应变曲线图,在此曲线上包含着一段线性比例关系的区域,此区域的材料行为符合所谓的虎克定律(Hook’sLaw) 弹性行为。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...

As the stress increases, the strain caused by it varies according to the properties of a material. The relationship can be limned by a graph, 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 ...
1(b). The region enclosed by the stress vs. strain curve has a close relation to the absorption energy against fracture; to put the matter simply, the alloy with larger area under the curve exhibits a better ability to absorb energy before fracture. The absorption energy, F, is generally ...
stress vs strain curve under uniaxial loading is shown inFig. 1.2a8and the important design parameters are the yieldstrength,tensile strength, uniform elongation and ductility or total elongation to fracture. The deformation beyond the elastic limit obeys a power relation between the true stress (σ...
Stress-strain curve A stress-strain curve is a graph derived from measuring load (stress - σ) versus extension (strain - ε) for a sample of a material. The nature of the curve varies from material to material. The following diagrams illustrate the stress-strain behaviour of typical material...

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(strain)之间的关系 遵循胡克定律,即: Stress=You...
