ultimate elongation

基本解释

Column 5 , the elongation at ultimate stress, in percentage gives an indication of the 'Toughness of the material.
第5栏，伸长率在极限应力项，在百分比给出了一个说明'韧性的物质。
The tensile strength of the ionomers increases and the ultimate elongation decreases with the increase of sulfonate content.
随着磺酸盐含量的增加，离聚体的拉伸强度增大，伸长率下降。
According to the testing and studying, ultimate strength, elongation and shrinkage on cross section of two kinds of steel bar were determined.
通过测试研究还得到两种钢筋的极限强度、延伸率和断面收缩率等其他高温力学性能参数。
