Abstract
This paper presents a fatigue-life prediction program which is written on an IBM PC computer. The main purpose of the computer program is to provide designers and engineers with a fatigue-life prediction program which encompasses the current state of the art in fatigue. The program is based upon the strain-life approach and takes into account mean stresses and size effects of geometric notches. Neuber's rule is used for relating remotely measured stresses and strains to stresses and strains at a notch root where plasticity dominates. The rainflow cycle counting technique is used to reduce complex load histories to a series of discrete events in order to assess the fatigue damage. Verification of the prediction program is made by conducting an experimental test program which involves ten different load levels combined with eight levels of mean stress.
