Abstract:
An investigation has been carried out, using statically loaded
steel and 'Perspex' discs, into elastic displacements occurring at the
axial extremities of the Hertzian flat.
By employing the technique of 'Photostress', together with optical
magnification, it has been found possible to inspect in detail the disposition
of strain around these points.
Using a 'step grinding' technique a qualitative three-dimensional
envelope of surface displacements has been constructed. The effect of
these displacements is considered in relation to 'edge pitting' of discs.
