Description

Volumetric characterization of composite delaminations was prioritized for rigorous composite damage progression modeling. In this study, angle longitudinal wave ultrasound was used to characterize simulated delaminations with distinct shadow regions in an isotropic medium. Simple representations of the specimen were modeled in CIVA to determine the optimal inspection parameters, including the transducer frequency and inspection angle. Experiments conducted with those optimal parameters provided visual evidence of the three-dimensional delamination field with indications from shadowed regions. The methods developed within this study serve as the foundation for more rigorous volumetric characterization of a delamination field within actual composite materials.
