真实/指数应变 即true strain / logarithmic strain:εtrue=lnL1L0 真实的应变,是基于变形后的长度积分得到的,因为表现形式是指数的形式,所以也可以称为指数应变。 名义/工程应变 nominal strain / engineering strain:εnominal=ΔLL0 名义应变,”名义“是指我们不考虑一步步的中间过程,只看开始和结尾,根据两者的...
工程应变，即名义应变，指的是在工程计算中，将初始长度与最终长度的比值作为应变的量度。它不考虑变形过程中的每一个微小步骤，简化了实际变形的复杂性，便于工程应用。真实应变，或称为指数应变，基于变形后的长度进行积分求得。真实应变的计算方法更接近实际变形情况，但由于其指数形式，因此得名。在材料...
Constant engineering strain rateStress-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 ...

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....
This review begins with an introduction to the macroscopic theory of crystal elasticity and microscopic effective low-energy Hamiltonians coupled with strain fields, and then summarizes recent advances in strain-induced optical responses of 2D TMDCs and graphene, followed by the strain engineering ...
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 ...
The ferromagnetism of these optimal EuO spin contacts was confirmed up to 58 K by SQUID magnetometry and all resemble the same M vs T behavior as shown in Fig. 8a, which agrees well with the silicide diminishment to the same minimum. Summary of the EuO/Si (001) interface optimization...
The most common NTM strain that infects humans is caused by Mycobacterium avium complex (MAC) [62]. However, MAC diseases represent a success story for inhalable treatments, with one commercially available liposomal-based treatment [63]. Severe acute respiratory syndrome (SARs) gained global ...
These models have and continue to improve our understanding of cancer; however, they are limited by strain-specific genetic backgrounds and cannot fully recapitulate the human TME (Klinghammer et al., 2017). To improve on the limitations of GEMMs, patient-derived xenografts (PDX...
