摘要： Non-limiting examples of the present disclosure relate to devices, systems and methods of manufacture for an exemplary waveguide usable for acoustic signal transmission for non-destructive evaluation (NDE) of a specimen (e.g., a wooden specimen) as well as apparatuses usable therewith. An exemplary waveguide comprises a mating portion for interfacing with a transducer horn of an ultrasonic transducer. The mating portion comprises at least a contact well configured to enable a connection between the transducer horn and the waveguide. The waveguide further comprises a body portion that comprises an upper body portion, that has a flat-faced distal end that is usable to establish contact with a surface of the specimen, and a lower body portion that is attached to and extends outwardly from the upper body portion and is further attached to the mating portion. Other technical examples are further described in the present disclosure.

摘要： Non-limiting examples of the present disclosure describe a non-destructive evaluation (NDE) application/service that is configured for NDE of a wooden specimen. The NDE application/service provides a user-friendly graphical user interface that enables inspectors to manage each phase of NDE of a wooden specimen through one or more computing devices. An exemplary NDE application/service is configured to analyze captured acoustic signal data (e.g., ultrasonic signal data) and transform that captured signal data into feature information that is used to more accurately assess the structural integrity of a wooden specimen. For instance, execution of a programmed NDE application/service employs a trained artificial intelligence (AI) classifier that evaluates waveform propagation (e.g., TOF and energy attenuation) through a wooden specimen to classify a condition and a quality the wooden specimen. An NDE report may be generated that provides an inspector with an assessment of the wooden specimen and/or a network of wooden specimen.

摘要： The technology disclosed relates to systems, methods, and devices for non-destructive evaluation (NDE) of a wooden specimen. A computer-implemented method for non-destructive evaluation of a wooden specimen comprises receiving acoustic wave signal data from NDE of the wooden specimen; processing the acoustic wave signal data to determine signal characteristics, such as an arrival velocity and amplitude attenuation of an AW2 mode; determining, based in part on a characteristic of the AW2 wave, an estimated strength metric of the wooden specimen; and displaying, on a graphical user interface associated with the computing device, an indication of the estimated strength metric of the wooden specimen.

摘要： Non-limiting examples of the present disclosure relate to devices, systems and methods of manufacture for an exemplary waveguide usable for acoustic signal transmission for non-destructive evaluation (NDE) of a wooden specimen. An exemplary waveguide comprises a mating portion for interfacing with a transducer horn of an ultrasonic transducer. The mating portion comprises an impact surface and a contact well that is fabricated within the impact surface so that the contact well is not contacted during an impact that drives the waveguide into wood. The contact well is utilized to connect the waveguide to a transducer horn. The waveguide further comprises a body portion that comprises a radiating component optimized for non-destructive evaluation (NDE) of wood and transmission of ultrasonic signal data. Further non-limiting examples describe an interfacing component for securing one or more devices to the waveguide as well as an extraction component that is configured to minimize damage to the waveguide during extraction.
