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。
In order to make asteroids that have long - ish oval or banana alike shape , ratio of maps has to be decided before going to anvil so that there ' s no stretching in the end 要创造出卵圆型或者像香蕉那样的小行星,就得在构建前决定贴图的尺寸比例以避免最后出现贴图的拉伸变形。
Gomez said doctors would start with the left side of casseus " skull and carve away the ballooning fibrous mass that had stretched and distorted her face , spreading apart her teeth 手术前戈迈兹曾说,医生将从卡苏斯的左脸开始手术,并且把导致她脸部拉伸变形的球状纤维组织切除掉。
In the present study , experimental investigations were carried out on the fatigue crack propagation characteristics of x60 pipeline steel after different degrees of pre - tension deformation ( 5 % , 10 % , 15 % ) 摘要用单边裂纹试样,研究了x60管线钢经预拉伸变形量为5 % 、 10 %和15 %后的疲劳裂纹扩展特性。
In this paper , the forming courses of the ribboning , bulge , expansive edge , cob - webbing and slough - off are analyzed . and the effect measures for overcoming these defects are provided 摘要分析了拉伸变形后卷装中出现的重叠、凸边、胀边、蛛网丝和脱圈等疵点的形成过程,提出了克服这些疵点的有效措施。
