Abstract

The three dimensional distribution of defects within a fatigue specimen cut from a large spheroidal graphite cast iron component has been obtained by X-ray computed tomography. This distribution has been used as input for a fatigue assessment postprocessor for the calculation of fatigue life distribution in cast components.
