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...
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 ...

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 ...
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....
The uncertainty of money coming in combined with the certainty of expenses—business or personal—means that having savings to fall back on when it’s a slow billing month can prevent a great deal of stress and give you enough flexibility that you aren’t forced into a corner with creditors...
Aluminum has higher stress relaxation than copper, experiences cold flow under moderate stress, has a higher creep rate and is more prone to fatigue. This behavior leads to a decrease in the connection clamping pressure during thermal cycling, which in turn increases the contact resistance, resultin...
Stress “What does not kill me makes me stronger”, Friedrich Nietzsche - Brutal, but with a grain of truth. “It is not the strongest of the species that survives, nor the most intelligent that survives. It is the one that is most adaptable to change.” Charles Darwin -A quoteto tame...
hello group, I have applied pure torque to the circular rod constrained at opposite end and examined the stresses, but i found that von mises stress so...
