Additional information

This continues the work presented in DOI:10.1063/1.3629772. The different wavemodes generated when using laser ultrasonics are studied, and propagation of these within a wedge-shaped sample is used to develop a new method of characterising the geometry of plates where the faces are not perpendicular, or identifying the angle of a wedge-shaped surface-breaking defect. This can be used alongside the enhancement and EMAT work presented in DOI:10.1016/j.ndteint.2011.02.001 to give a full geometry of surface-breaking defects in e.g. railway tracks. This method of scanning has since been used by other research groups, e.g. 10.1002/stc.1504.
