The maximum represents a significant difference between the engineering stress-strain curve and the true stress-strain curve. In the engineering stress-strain curve, this point indicates the beginning of necking. The ultimate tensile strength is the maximum load measured in the tension test divided by...

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....
Using this information, compute the engineering stress necessary to produce an engineering strain of 0.25. Engineering Stress and True Stress: Trues stress is defined as the ratio of instantaneous force to the instantaneous cross-sectional area where as engineering stress is defines as...
Stress-strain curveMaterial responseIn this study, a Johnson-Cook model was used as an example to analyze the relationship of compressive stress-strain response of engineering materials experimentally obtained at constant engineering and true strain rates. There was a minimal deviation between the ...
Conversant with engineering stress analysis formula and is capable of applying them correctly. 熟悉工程压力分析公式并能正确进行运用; www.jobui.com 2. The present size effect law for the engineering stress-engineering strain curve is also agreement with earlier numerical results. 工程应力应变曲线尺寸效...
The strain used for the engineering stress-strain curve is the average linear strain, which is obtained by dividing the elongation of the gage length of the specimen,d, by its original length. (2) Since both the stress and the strain are obtained by dividing the load and elongation by cons...
Based on this, some scholars have derived similarity ratios of other physical parameters, including stress similarity ratio, elastic modulus similarity ratio, Poisson's ratio similarity ratio, and strain similarity ratio, by combining equilibrium equations, physical equations, compatibility equations, ...
