摘要： Methods that provide wrinkle characterization and performance prediction for wrinkled composite structures using automated structural analysis. In accordance with some embodiments, the method combines the use of B-scan ultrasound data, automated optical measurement of wrinkles and geometry of cross-sections, and finite element analysis of wrinkled composite structure to provide the ability to assess the actual significance of a detected wrinkle relative to the intended performance of the structure. The disclosed method uses an ultrasonic inspection system that has been calibrated by correlating ultrasonic B-scan data acquired from reference standards with measurements of optical cross sections (e.g., micrographs) of those reference standards.

摘要： Provided are methods and inspection systems for evaluating height deviations on surfaces of composite structures. The method is based on obtaining multiple linear height profiles of a surface and generating a three-dimensional representation of that surface. This representation is then analyzed to determine various height deviations, such as wrinkles. The three-dimensional surface representation is generated based on position of each linear height profile on the surface. The analysis may be performed along any direction, which may be different than the inspection directions of to the linear height profiles. As such, height information from multiple height profiles is analyzed at the same time. This approach increases the quality of inspection and ensures that different types of height variations can be identified, which may be missed with individual analysis of each linear height profile. Furthermore, this approach allows using high precision linear height detectors, such as laser profilers.

摘要： The present disclosure is generally directed to of method linear feature detection in a structure by providing a first digital image of the structure, creating a second corresponding digital image of the structure from the first digital image and determining a direction to shift pixels of the second corresponding digital image. A pixel shift value may be input to shift pixels of the second corresponding digital image, and pixels of the second corresponding digital image are shifted by the input pixel shift value in the determined direction. A third corresponding digital image of the structure may be calculated by subtracting the second corresponding digital image of the structure from the first digital image of the structure.

摘要： A method of detecting a compound in a material sample is presented. A transformation is generated from a set of IR spectra of a set of identified compounds, in which the compound is one of the set of identified compounds. The transformation is applied to an IR spectrum of the material sample to form a transformed IR spectrum. A decomposition is applied to the transformation. Results indicative of a presence or an absence of the compound are generated based on an output of the decomposition.

摘要： The present disclosure provides a system, method, and apparatus for compressing and extracting features. The method involves transmitting at least one ultrasound signal into an object at a plurality of different locations on the object. Each of the locations is denoted by an x location and a y location. The method further involves receiving at least one waveform response signal. Also, the method involves generating a three-dimensional (3D) data cube with an X dimension, a Y dimension, and a time dimension. At least one waveform response signal is stored within the 3D data cube at the x location and the y location that is associated with the waveform response signal(s). Further, the method involves transforming at least one waveform response signal of the 3D data cube to produce at least one transformed signal.

摘要： Composite skin-stringer structures which reduce or eliminate the risk of delamination at the skin-stringer interface. This can be accomplished by arranging ply directions (i.e., the angles of the fiber paths of the ply) in a layup in a way such that for the dominant loading, the skin and stringer will each deform in a way that reduces relative opening (fracture Mode I) and/or sliding (fracture Mode II) and/or scissoring (fracture Mode III) at the skin-stringer interface. This is possible when coupling between specific deformations modes is purposefully activated instead of being suppressed. The ply directions in the stringer are adjusted so that the stringer deforms in a controlled fashion to suppress or “close” cracks that are about to form—before the undesirable modes of failure form—as load is applied.

摘要： A system comprises a model generation system and an analyzer. The model generation system is configured to modify a model of a laminated composite structure to meet a user defined objective and to meet at least one of user defined performance constraints or user defined manufacturing constraints by changing at least one ply characteristic of at least one ply of the model while maintaining ply boundary geometry constraints for each ply of the model. The ply boundary geometry constraints of the model generation system include a number of defined ply boundary geometries each described by a respective mathematical function. The analyzer is configured to return objective values or constraint function values for at least one ply of the model.
