Computational Geometry-Based 3D Yarn Path Modeling of Wound SiCf/SiC-Cladding Tubes and Its Application to Meso-Scale Finite Element Model

The filament winding process is a competitive performing technology for nuclear fuel cladding tubes due to its high automation. study of the yarn path on mandrel surface vital design and produce tube with desired mechanical properties, reducing manufacturing time costs. geodesic semi-geodesic trajectories are used create 3D in this paper. A optimization method based principle minimum potential energy proposed simulate overlap effect accord real process. finite element (FE) mesh has been analysis tube. embedded region constraint applied define interaction between matrix model meso-structure Based meso-scale FE model, behavior wound SiC f /SiC studied detail. results show that neglect effect, conventional laminate overestimates strength. can accurately predict failure also confirm creation derived representing an accurate structure, importance prediction performance
