摘要： Methods for generating a flat pattern for a composite ply. A method includes receiving a tool model and a ply coverage, wherein the ply coverage defines a plurality of plies, a fiber orientation for each of the plies, and a boundary for each of the plies, determining one or more subset regions on the tool model based on the boundaries from the ply coverage, creating a merged ply combining the plies and aligning the fiber orientations, defining staging instances of the merged ply for each ply covering a subset region, determining a laydown order of the staging instances, running a draping simulation using the laydown order to solve the staging instances, generating a flat pattern from the draping simulation, and storing the flat pattern of the composite ply.

摘要： Methods for product data management and corresponding systems and computer-readable mediums. A method includes receiving one or more layer boundaries of one or more plies of a composite part. The method includes creating a topological definition from the layer boundaries, the topological definition includes one or more vertices and half-edges. The method includes identifying one or more vertical ramp sections of one or more vertical ramps from the topological definition that form one or more discontinuities in the topological definition. The method includes adding one or more additional vertices and half-edges to the topological definition based on the layer boundaries and the vertical ramp sections. The method includes creating one or more faces in the topological definition along the vertical ramp based on the additional vertices and half-edges to resolve the discontinuities. The method includes transmitting the topological definition with the faces.
