Measurement of delamination crack tip displacement in G/E laminates using scanning electron microscopy
A method of measuring delamination crack tip displacements in graphite/epoxy specimens in a Scanning Electron Microscope (SEM) is presented. The technique involves the application of a grid to the specimen edge by evaporating a layer of gold through a thin mesh. The specimens are then placed into a …

An assessment of the fracture toughness of two cast and wrought stainless steels
The crack-tip displacement concept has been applied to austenitic steels at 25°C and in the temperature range 400-800°C. The measurement of a maximum load crack-tip displacement in a notch bend test, provided a good indication of fracture-toughness since it included a portion of slot: crack-growth. …

High resolution fatigue crack growth analysis of crack closure and slip irreversibility using digital image correlation
Crack closure and slip irreversibility in the fatigue crack growth of 316L stainless steel were investigated using digital image correlation (DIC). A polycrystalline and a oriented specimen were tested to study mode I fatigue crack growth, while oriented specimens were used to study mixed mode (I …
