Examples
- Prestressed concrete sleepers - pretensioning type
预应力混凝土轨枕.预拉伸型 - Study on production process of 2d70 - t651 aluminum alloy plate
651铝合金预拉伸厚板生产工艺研究 - After pretension 0 . 1 strain and pretorsion to 14 , whereas the strength limit keep on increasing in company with the pretorsional capacity
其中屈服极限在预拉伸应变0 . 1后再预扭转14后达到最大值，而强度极限随着预扭转量的提高不断增大。 - Test results showed that the fatigue crack propagation rare increased with increasing the pre - tension deformation degree , especially at the near threshold section
结果表明：随著预拉伸变形量的增加，疲劳裂纹扩展速率提高，尤其是在裂纹扩展的近门槛区。 - The residual stresses in the thick aluminum alloy plates of ly12 , b95 . and 7050t7451 are measured , and the results are analyzed and compared
在此基础上,首次对国产ly12 、美产7050t7451和俄产b95 .三种典型的铝合金预拉伸板内部初始残余应力分布进行了测试和对比分析。
