    摘要： Method and system are disclosed for characterizing and quantifying composite laminate structures. The method and system take a composite laminate of unknown ply stack composition and sequence and determine various information about the individual plies, such as ply stack, orientation, microstructure, and type. The method and system distinguishes between weave types that exhibit similar planar stiffness behaviors, but which produce different failure mechanisms. Individual ply information then is used to derive the laminate bulk properties from externally provided constitutive properties of the fiber and matrix, including extensional stiffness, bending-extension coupling stiffness, bending stiffness, and the like. The laminate bulk properties are then used to generate a probabilistic failure envelope for the composite laminate. This provides the ability to perform non-destructive QA to ensure that individual lamina layup was accomplished according to specifications, and results are used to identify numerous laminate properties beyond purely structural ones.

    摘要： A calibration method includes receiving data characterizing a plurality of acoustic signals reflected by a defect in a target object, and a first depth of the defect relative to a surface of the target object. A first acoustic signal and a second acoustic signal are detected by a detector at a first location and a second location, respectively, on the surface of the target object. The plurality of acoustic signal includes the first acoustic signal and the second acoustic signal. The method also includes determining an envelope function based on at least the first acoustic signal and the second acoustic signal. The method further includes identifying a target distance between the detector and the defect. The target distance is associated with a peak value of the envelop function. The method also includes calculating a detection angle based on the target distance and the first depth of the defect.

    摘要： A compact portable ultrasonic inspection apparatus and method of non-destructive inspection of an object. A probe of the apparatus has a stationary cavity frame assembly with an agile ultrasound stylus, being a transducer and an acoustic coupling member, located therein and on which a motion system induces random or controlled motion of the stylus, to pivot the transducer about a point where the coupling member contacts a surface to be inspected. Three landing elements surround the coupling member, configured to hold the frame assembly to the surface. A sequence of oblique angle ultrasound measurements collected at measured transducer orientations generate polar scans of backscattered acoustic energy from within the object and automatically derive geometric measurements and/or ascertain internal health-condition information about the object. The apparatus finds application in-situ non-destructive testing (NDT) inspection of anisotropic or composite materials used in safety-critical objects or structures.

    摘要： Systems and methods for inspecting or characterizing samples, such as by characterizing patterned features or structures of the sample. In an aspect, the technology relates to a method for characterizing a patterned structure of a sample. The method includes directing a pump beam to a first position on a surface of the sample to induce a surface acoustic wave in the sample and directing a probe beam to a second position on the sample, where the probe beam is affected by the surface acoustic wave when the probe beam reflects from the surface of the sample. The method also includes detecting the reflected probe beam, analyzing the detected reflected probe beam to identify a frequency mode in the reflected probe beam, and based on the identified frequency mode, determining at least one of a width or a pitch of a patterned feature in the sample.
