Resonance inspection of manufactured parts with witness coupon testing
Resonance inspection of parts in which a resonance standard to which a frequency response of the part is compared is at least in part based on a property derived from testing of a witness coupon that is manufactured concurrently with the part. This approach may allow properties of a material and/or manufacturing technique used to produce the part and witness coupon to inform the resonance standard to improve testing. Approaches are described related to both empirically derived resonance standards as well as model-based resonance standards.
