Scattering of SH Waves by Cracks and Delaminations in a Cladded Plate
Recent investigations of space construction have explored the use of Al cladded graphite/epoxy materials for space platforms. Characterization of potential flaws and joints in the cladded material by non-destructive evaluation (NDE) methods ensures the reliability of the structure. One possible NDE method is to use anti-plane shear (SH) waves generated and detected by electromagnetic-acoustic transducers (EMATs). There have been some investigations on the interactions of SH waves with delamination defects in a bimaterial plate. References to some of these can be found in Kundu[l,2]. Scattering of SH waves by cracks in a homogeneous plate was studied by Abduljabbar, et al. [3–5].
