Abstract
Three-dimensional (3D) images of a thumbnail corner fatigue crack are obtained in a sample of nodular graphite cast iron using laboratory X-ray computed tomography. The crack is initiated in situ from an artificial defect created by laser machining, its development is followed in situ and Digital Volume Correlation (DVC) analysis of the 3D images gives access to the 3D displacement field at the tip of the crack (mainly mode I opening).
