与expansion bend相关的网络例句 [注：此内容来源于网络，仅供参考]

The results show that, with the expansion cone angle remaining unchanged, the sizing length of expansion cone does not have much effect on the residual stress of casing after expansion, but it has much effect on the expansion force required by tube expansion. The expansion cone angle has no effect on the maximum residual stress of casing, but it has remarkable effect on expansion force. When the radial component force of expansion force is greater than the material's tensile strength, the damage to the material will arise.

研究结果表明，在膨胀锥锥角保持不变的情况下，膨胀锥定径长对膨胀后套管的残余应力没有太大影响，但对套管膨胀所需要的膨胀力有较大影响；膨胀锥锥角对套管最大残余应力没有影响，但对膨胀力的影响十分明显，当膨胀力的径向分力大于材料的抗拉强度时，材料将发生破坏。

The invention orginates from the fact that most of the concrete reinforcement loops needed in practice can be divided up into relatively small number of types of loops which are characterized by a predetermined sequence of points of bend with a fixed sense of direction and amount of the angle of bend, in which case the loops of the same type differ from one another only in the lengths of the individual sides of the loops between the points of bend, or from one end of the loop to the first point of bend, and from the other end of the loop to the last point of bend.

问题补充：不要软件翻译的，最好自己翻译，起码通顺的这项发明orginates的是钢筋混凝土的循环需要在实践中最可分为相对的，是由弯曲点的序列特征与预定的方向和角度的数额固定感循环类型的为数甚少的事实弯曲，在这种情况下，同类型的循环，从彼此的不同只是在弯道之间，或从一个循环结束第一点弯曲点的循环个人边长，从另一端循环的最后一点弯曲。

Vesic's solutions to cavity expansion that include cylindrical cavity expansion and spherical cavity expansion are introduced. Then cylindrical cavity expansion theory is applied to study compaction effect of pile driving in saturated soil. Based on the results of conventional triaxial tests, a trilinear curve model is used to simulate stress-strain curve of strain-softening materials. Meanwhile, trilinear curves are also used to simulate curves of volumetric strain, minor principal strain and major principal strain. By using elasto-plastic theory, analytical solutions to cylindrical cavity expansion in strain-softening soil are presented. According to the mechanism of statically pressed pile driving, compaction effect of pile tip can be viewed as hemispheric cavity expansion. Therefore spherical cavity expansion theory is applied to obtain the solutions to stress, strain, displacement fields and final pressure. Resistance force of pile tip is calculated to estimate static pressure.

介绍了Vesic关于圆孔扩张问题的解答，其中包括柱形孔扩张问题和球形孔扩张问题，并应用柱形孔扩张理论分析了饱和软土中的沉桩挤土效应问题；在常规三轴试验成果的基础上，采用三折线模型模拟具有应变软化性质的岩土材料的应力应变关系曲线，分析了在应变软化土体中沉桩时桩周土的位移场、应力场和应变场的变化，得到了解析解答；分析了静压桩的沉桩机理，并利用球形孔扩张理论，视桩端处的挤土为半个球形孔的扩张，分析了桩端处土的位移场、应力场和应变场的变化，并根据最终扩张压力计算出沉桩时的桩端阻力，可作为压桩力的估算。
