Abstract: Various approaches for assessing a part for a defect are disclosed and that are based upon SAW modes. In one embodiment, a part-under-test (120) is excited. One or more SAW modes (206) are identified in the frequency response (240/260) of the part-under-test (120). A SAW mode area (248/266) in the frequency response of the part-under-test (120) is compared with a baseline SAW mode area (238/258) of a baseline frequency response (230/250) (and which may be associated with an acceptable part). This comparison may be used to determine if the part-under-test (120) may be characterized defective in at least some respect.

In order to scan an internal structure of an O-ring, the present disclosure includes an apparatus with an apparatus body to which an O-ring support and a transducer assembly are attached. The transducer assembly includes an ultrasound generator that transmits ultrasound toward the O-ring to generate reflections toward an ultrasound receiver. The apparatus includes a display for comparing ultrasound receiver data with expected data. It is determined whether there are reflections of the ultrasound transmissions off of at least one internal surface within the O-ring.

Abstract: A method for determining warp potential of wood. One embodiment comprises nondestructively obtaining lengthwise shrinkage rates and grain angles of wood—such as trees, logs, or lumber—then determining warp potential of the wood based on the lengthwise shrinkage rates and grain angles. The method typically comprises measuring plural lengthwise shrinkage rates and plural grain angles to determine warp potential. Where the wood comprises lumber, lengthwise shrinkage rate and grain angle measurements typically are made on at least one major planar surface of the lumber at at least two measuring points separated by a predetermined distance, such as at substantially one-foot intervals along the lumber. Particular embodiments of the present invention determine lengthwise shrinkage rates using electromagnetic energy, acoustic energy, and combinations thereof. Working embodiments of the method use ultrasound energy to determine lengthwise shrinkage rates and grain angles. Another embodiment of the present invention comprises providing a piece of wood having at least one major planar surface, positioning the piece of wood adjacent to a device for imparting energy through the piece of wood to determine at least one lengthwise shrinkage rate and at least one grain angle. Embodiments of the present invention are automated and can be adapted to industrial processes for commercial production of lumber or for forest management practices. Warp potential can be determined using a finite element model (FEM).
