Directivity patterns of ultrasonic waves generated by a laser pulse at the interface between two elastic media

Abstract : Directivity patterns of an acoustic source generated by the absorption of a laser pulse at the interface between a transparent epoxy-resin half-space and an opaque CFRP isotropised half-space have been calculated using the reciprocity theorem. Longitudinal and shear radiation patterns of acoustic field emitted in the CFRP are compared in respect with the loading surface condition.
