Abstract:
1. A method for generating at a computing platform, including a memory and a processor, a non-destructive inspection model for a composite part from a design model of the composite part, the method comprising: analyzing, by the processor, a design model file stored in the memory to determine a plurality of properties of the composite part, the design model file describing one or more physical characteristics of the composite part and comprising a computer aided design (CAD) model file for the composite part; analyzing an area of interest of the CAD model file corresponding to a region of the composite part selected by a user; generating, by the processor, a non-destructive inspection model for the composite part based on the plurality of properties of the composite part determined by analyzing the CAD model file by converting the area of interest into a volume of interest by formulating an arbitrarily oriented minimum bounding box that encompasses voxels corresponding to material contained within the area of interest; and constructing a set of voxel models from cross section bitmaps of the composite part, by extruding the cross section bitmaps, such that non-destructive inspection simulation is performed on the set of voxel models; wherein the composite part comprises a portion of an aerospace component comprising at least one of carbon fiber reinforced polymer (CFRP) and/or graphite fiber reinforced polymer (GFRP); and wherein the plurality of determined properties of the composite part comprise at least one of a density of the composite part, a speed of a given acoustic wave in the composite part, an orientation of plies for the composite part, a layer layup rule for the composite part, a layer layup order for the composite part, a description of layer interply for the composite part, and an overall geometry for the composite part.
