剪切面

The wall is, also here, marked by sheers, commonly talcose, and the beds of phyllite are cut and dragged by the movements.

在这里，上盘一般见滑石化的剪切面，千枚岩层被构造运动所切割并产生拖曳。

Similarly the stress gradient across the shear plane has to be very large to be practical.

同样在实际运用中越过剪切面的应力梯度必须很大才行。

There were same trend of temperature distribution in rake plane and shear plane, and the feasibility of numeric simulation through was validated through comparing the result of experiment with simulation result.

通过对数值模拟结果和试验结果的比较，在前刀面和剪切面上温度分布具有相同的趋势，验证了数值模拟的可行性。

In view of the questions in theoretic analysis and numerical simulation with the finite element method,the separation criterion of chips, the surface contact, the setting of friction coefficient,and the thermal stress coupling are researched. A simulation example is presented by applying the finite element analysis software-ANSYS,and the change of stress and strain in metal cutting process, the forming of shear plane and the influence of the temperature field on metal cutting are analyzed. The tool's strength is also analyzed.

基于理论分析和实际有限元数值模拟计算中遇到的问题，研究、讨论了切屑分离标准、表面接触、摩擦系数的设定、切屑与工件之间的连接以及热应力耦合分析等各项技术，并应用大型有限元分析软件ANSYS，具体分析了金属切削过程中应力和应变的变化、剪切面的形成以及温度场对金属切削的影响，并依此对刀具作强度分析，得到若干结论。

The reasons why quarter-sawn board of Larch had smaller wet compressing shear strength than flat-sawn board of Larch for repeatedly boiling samples were as follows: first of all, antiswelling efficiency between springwood and summerwood of Larch was different; secondly, pits of Larch had great effect on this aspect.

造成桦木反复煮沸压缩剪切强度径切板的比弦切板的要大的主要原因是在弦切面木射线是被横断的，因此，在弦面上留下射线管胞的孔隙，在反复煮沸时这些孔隙成为了水分的通道，因而使桦木反复煮沸压缩剪切强度径切板的比弦切板的要大。

This provides an even radial cut for full bore re- entry compared with the belled over profile of sheared pipe.

与剪切的管子喇叭口剖面相比，这可为全径返回井口提供均匀的径切面。

It studied many factors such as blank holder pressure, anti-pressure, clearance between punch and bottom die, and parameters of dentiform on blank holder, analyzed the influence of these factors' change to stress and strain field in distortion area and the appearance of shear crack, summarized the appropriate ratio of blank holder pressure and anti-pressure, and the best range of other factors.

从压边力、反压力、相对冲裁间隙、压边圈齿形参数等各种因素出发，分析了这些因素的变化对于变形区应力应变场与剪切面裂纹产生的关系，并得出了压边力与反压力的合适配合比例，以及其他参数的正确取值范围。

The results show that some twin crystals and honeycomb structures appear in the shear plane and many kinds of deformation mechanism exist such as extruding, kinking and so on. When annealed at 550 ℃ for 2 h, the recrystal gains are observed in the shear plane. Especially the side receives the cut of guillotine, the size of recrystal grain is very thin, corresponding with the recrystal grains obtained by cold rolling at 80% deformation rate.

结果表明：经剪切变形后，切面处形成一种独特的带状变形孪晶和蜂窝状变形组织，且存在挤压、扭折等多种变形机制的作用；合金在550 ℃退火2 h后，切面出现许多再结晶晶粒，且在承受剪床切口的一边再结晶晶粒非常细小，相当于冷轧变形80%后的再结晶晶粒尺寸。
