In situ 3D characterization of fatigue cracks displacement fields

Journal Title: Frattura ed Integrità Strutturale - Year 2013, Vol 7, Issue 25

Abstract

 The three dimensional growth of fatigue cracks in samples of nodular graphite cast iron is characterized using laboratory X-ray computed tomography. The cracks grow from laser machined artificial defects, their development is monitored in situ using laboratory X-ray  computed tomography (lab. CT) and Digital Volume Correlation (DVC). The combination of both techniques gives access to the 3D displacement field at the tip of the crack (mainly mode I opening).
