V型切口对06Cr19Ni10钢低周疲劳寿命的影响
Effect of V-Shape Notch on Fatigue Life of 06Cr19Ni10 Steel
摘要
Abstract
Different depths are cut in the smooth specimen. When the stress ratio R = - 1 and the loading amplitude is symmetry and constant, the axial tension and compression fatigue tests is conducted. The life of specimens can be got when depth and incision angle are different. The S—N curve can be fitted in the bi - logarithm coordinates. When incision depth is constant value,the life of specimens decrease with the stress increasing. In addition, a deeper incision could lead to shorter life of specimen and the relationship between the notch depth and life is nearly linear. When the incision angle is between 30° and 60p ,it has no effect on the service life关键词
