摘要
通过测定不同材质PVC-U管材的拉伸性能,分析其在拉伸过程中试样截面积和密度的变化及应力-应变曲线的不同,讨论了不同材质PVC-U管材拉伸屈服点判定方法、真应力、拉伸机制的差异。
The tensile properties of PVC-U pipes made from different materials were determined.The specimens’changes in sectional area and density during stretching were analyzed as well as the difference in stress-strain curves.The difference between PVC-U pipes made from different materials in decision method of tensile yield point,true stress and tensile mechanism were discussed.
