Finite-strain constitutive relationship based on Oldroyd objective rate of Kirchhoff stress by τ-γ curve of torsion test with cylindrical specimens is presented.

以扭转实验测得的τ-γ曲线为基础，采用各向同性硬化大应变J2流动本构理论，给出了基于Kirchhoff应力的Oldroyd客观导数的塑性刚度函数h的表达式，建立了相应的大应变本构关系。

Models of middle-segment oblique fracture without defects were established and fixed by 14-hole stainless steel AO limited contact-dynamic compression plate, using 6, 10, and 14 screws separately. The stress-strain index under torsion, three-spot bending and compression of the complete fresh tibia was determined again statistical analysis.

然后制成中段斜行无缺损骨折模型，以14孔不锈钢AO有限接触型动力加压接骨板固定，分别使用6， 10， 14枚螺丝钉，测定扭转、三点弯曲、压缩等应力－应变指标，进行统计学分析。

The VCL method and the displacement method are used to calculate the Stress Intensity Factors of semi-elliptical surface crack at the root of pipe screws, on the basis of which a simplified calculating model for screws contact is put forward so as to analyse the fracture intensity for oil drill pipe screw coupling. For the semi-elliptical surface crack with different shape and deep ratio at the root of female and male screws and the corner of male flange, the SIF has been studied systemically under inter-pressure, tension, bend and torsion loads and the approximate formulas encluding the structure parameters of oil drill pipe screw coupling, deep ratio and the shape parameters of surface crack are developed.

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
