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...
At the outset, though, a clear distinction must be made between a true stress-true strain curve and an engineering stress-engineering strain curve. The difference is shown in Figure 2, which are plotted, on the same axes, the stress-strain curve and engineering stress-strain curve for the s...

A significant difference between the true stress strain and the engineering stress strain has been observed. Based upon the definitions of true stress and ... Y Li - 《Journal of Chongqing University》 被引量: 26发表: 2001年 True Stress-True Strain Models for Structural Steel Elements A standa...
An engineering procedure is proposed for assessment of the stress state of elliptical bottoms with set-on nozzles as a function of their size. Diagrams and approximating equations to define stress-enlargement ratios, which are used to calculate brittle-fracture resistance and evaluate the cyclical ...
Engineering stress, s, is defined as load divided by the original cross sectional area of a specimen, and elongation or strain is obtained by dividing elongation of the specimen gauge length by its original length. From: Encyclopedia of Materials: Science and Technology, 2001 ...
Therefore, we cannot confidently conclude that there is a true difference in house comfort perception among the participants based on the data analyzed. However, it’s important to interpret these results with caution, considering that the p-value is close to the confidence boundary. Despite the ...
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 ...
3.2.7Mechanical stress and applications of mechanical foam breakers Mechanical foam destruction exposes the cell-containing liquid in the foam to mechanical stress. The application of this technology is, therefore, limited to biological systems that can resist mechanical forces to a certain threshold. ...
