真实应力Ture Stress为: σTrue=NA A -- 拉伸后的横截面,变小 工程应力/名义应力Engineering Stress/Nominal Stress为: σNominal=NAo Ao-- 原始横截面 结论 σTrue>σNominal 实际工程计算中,我们采用σNominal。 因为:相对于实际工程计算的大数值,和σTrue和σNominal之间的数值变化较小,使用σNominal不影响实际...
You can notice that, unlike the engineering stress curve, the true stress curve goes on increasing.Stress-strain curve for true and engineering data. Example: Using the true strain calculator Find the true stress for nominal stress of 8 MPa. Take nominal strain as 0.1. To find the true ...

The true stress s is expressed in terms of engineering stress s by (1) The derivation of Eq. (1) assumes both constancy of volume and a homogenous distribution of strain along the gage length of the tension specimen. Thus, Eq. (1) should only be used until the onset of necking. Beyon...
摘要: The article deals with a possibility of structure of approximate true stress-true strain diagram using the engineering stress-strain curve and mechanical properties of material. A possibility to define the curve more precisely behaind the point of instability is demonstraited....

Examination results showed how much the magnitude of true stress, determined for plastic strain range, differs from the magnitude of the engineering stress. The tests that were carried out enabled to analyse the participation of elastic strain in the range of uniform elongation of thin wires. It ...
aThe true stress-strain curves are then calculated with the equations (3.2) and (3.3), in which σ and ε are the true stress and strain and s and e are the engineering stress and strain. 真压力类型的曲线然后跟等式一起被计算 (3.2) 和 (3.3),其中 s 和 e 是真的压力和紧靠和 s 和 ...
However, the true stress behavior was found to be not only quantitatively but also qualitatively different from that of the engineering stress. Highly localized deformation results in abrupt increases of the true stress in certain regions, favoring crack formation and propagation. The computer-generated...
