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).

A new micromechanical model of CNT-metal nanocomposites with random clustered distribution of CNTs
Uniform dispersion of carbon nanotubes (CNTs) is a key issue for utilization of their reinforcement potential in CNT-reinforced metal matrix nanocomposites (MMNCs). It was reported that CNT clusters often exist i...
Experimental investigation of fibre reinforced plastics with hybridlayups under high-velocity impact loads
This paper deals with experimental investigations concerning energy dissipation capacity ofdifferent kinds of reinforcement fibres in monolithic and hybrid layups under high-velocity impact loads. Theinvestigated k...
Extension of the CJP model to mixed mode I and mode II
The present authors have previously proposed a novel ‘plastic inclusion’ approach for dealing with the local plasticity which occurs at the tip of a growing fatigue crack. This meso-scale model provides a mod...
