Finite Element (FE) Shear Modeling of Woven Fabric Textile Composite

摘要

This paper demonstrates the modeling of woven fabric textile composite under in-plain shear loading. The geometric modeling of fabric unit cell is modeled using TexGen textile modeling schema developed at the University of Nottingham. The yarns in the present scheme are treated as solid volume whose modeling depends upon various parameters such as yarn path, yarn cross-section, yarn surface. Periodic boundary conditions were identified to simulate the realistic nature of repetitive fabric unit cell. Transversely isotropic material law with non-linear transverse mechanical properties is incorporated using finite element (FE) simulation software ABAQUS~R. This approach is initially validated for pure in-plain shear and compression loading; later on it is used to simulate the behavior of fabric under the combination of these loads which practically occurs during forming process. A successful prediction of shear force versus shear angle are made and was found that the majority of the energy being dissipated at higher shear angles due to yarn compaction. The scope of altering weave pattern and yarn characteristics is facilitated in this developed model.
