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...

The effective plastic strain values input in defining a stress vs. effective plastic strain curve in a LS-DYNA plasticity model should be the residual true strains after unloading elastically. True stress is input directly for the stress values. Using experimental data from a true stress vs. tru...
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....

📖 David Allen, Getting Things Done: The Art of Stress-Free Productivity: while it could be much shorter, this book is probably the best way to learn about the GTD methodology. Productivity 101: A Primer to the Getting Things Done (GTD) Philosophy: a great summary of GTD. Zen Habits:...
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 ...
Cold working steel or aluminum involves subjecting the material to mechanical stress at low temperatures. This process causes the material to become harder and stronger due to the formation of dislocations and grain boundaries. However, it also leads to a decrease in ductility, which refers to ...
