摘要
借助两种不同类型的引伸计,自动测定冷轧薄板断后伸长率A。将两种方法得到的试验结果进行比较,发现用非接触式引伸计自动测量的断后伸长率具有较高的可靠性和重现性。
The percentage elongation A of the cold-rolled thin sheet after fracture was measured automatically by two different extensometer： contact and non-contact. Comparing the results by two different methods, finds that the results of using video-extensometer shows high reliability and repeatability.
