Two-dimensional model of triangular sectors for use in generating a mesh for finite element analysis

摘要

A method and apparatus for analyzing a joint. The apparatus comprises a graph generator and a model generator. The graph generator forms a first graph based on a plurality of points within a region. The plurality of points represent a plurality of locations relative to a structure for a plurality of fastener devices configured to be installed in the structure to form a joint. The graph generator is configured to identify primary points and secondary points based on the first graph. The graph generator is further configured to form a second graph using the primary points, the secondary points, and the first graph. The model generator is configured to generate a two-dimensional model comprised of triangular sectors using vertices of the second graph. The two-dimensional model is configured for use in forming a mesh for use in performing finite element analysis for the joint.
