Finite Element Modeling Of Three Dimensional Textile Composites RVE Enhance Phase

Three-dimensional textile composites have been more and more widely used in industry,automobile structures and aerospace fields. The types of internal reinforcement fibre bundlestructures of textile composites is quite a lot. And mechanical properties of three-dimensionaltextile composites depend largely on the internal reinforcement structures. Therefore, in-depthstudy of the geometric properties of the internal architecture of the textile composites hastheoretical and practical significance for the prediction of their mechanical properties.As the geometries of the reinforcement structures in the textile composites are verycomplex, numerical methods have been widely used to predict their mechanical properties.However, because of textile composites have a high degree of heterogeneity, and structure isvery complex, and makes the textile composites finite element modeling is very difficult. Thispaper learn from Professor Jiang Wenguang of domain superposition technique (DST) offinite element modeling strategies that will matrix materials and fiber body materials of thefinite element model of established separate, cleverly avoided the to contain fiber bundles ofstrange shape of the geometrical model of substrate material. And compared with thetraditional finite element modeling method, this method is more easy to build finite elementmodel.The major objective of this thesis is to establish the system of the finite element model ofseveral main types of textile composites internal enhance phase structure. As a powerfulABAQUS finite element analysis software, is widely used, this article, under the environmentof ABAQUS, using ABAQUS interface language Python a systematic several major types oftextile composites structure parameter of internal enhance finite element model. The modelfor the follow-up to the textile composites performance prediction to lay the foundation.
