摘要
文章介绍了永久变形的发生机理,拉伸和压缩永久变形的差异及应用现状,拉伸和压缩永久变形测试在实际应用中的差别以及拉伸永久变形测试的必要性,拉伸永久变形对伸张疲劳性能的影响等,说明了在实际应用中不能忽视拉伸永久变形测试,并建议尽快建立相关的国家标准。
This article introduces theory of tension set, difference between tension set and compression set and application status, the difference of application between tension set and compression set and the necessity of tension set test, the influence of tension set in tension fatigue test, etc., which illustrates that tension set test can not be ignored in application. The suggestion to develop concerned national standard is provided
