Abstract

The detection and location of holes in an isotropic aluminium plate using fibre Bragg grating rosettes to detect ultrasound Lamb waves is described. This is followed by a description of the anisotropic properties of a carbon fibre plate and their effect on hole detection. Finally, the issues involved in attempting to locate holes in an anisotropic samples are discussed and the possibility of achieving this assessed
