Abstract

The influence of surface roughness on fatigue limit is evaluated by a surface factor and a safe factor and they don't have the distinct physical meanings. To discuss a quantitative evaluation of surface roughness on fatigue limit reliability, the exact solution is given for a problem of an infinite plate with a complex profile under tension. The solution is obtained with the complex variable method. Some simple periodical notch problems are analyzed with the solution and also the method is shown to solve a problem of a complex profile.
