Stress analysis of 3D textile composites using high performance computing: new insights and challenges Conference Paper uri icon


  • Published under licence by IOP Publishing Ltd. A finite element analysis (FEA) framework that leverages high-performance computing (HPC) was used to analyze a non-idealized 2x2 orthogonally woven textile model, which was created using VTMS. Since the geometry was not idealized, simple boundary conditions were applied to a large analysis region and an interior subregion was used for investigating the stresses. The variation of the cross-sectional area was investigated, showing that the area varied by 26% within the tows near the top and bottom of the textile model. However, tows near the middle of the textile experienced very little variation in the cross-sectional area. The locations of severe stresses were investigated for two configurations: uniaxial tension along the binder direction and uniaxial tension transverse to the binder direction. It was shown that transverse tension in the tows perpendicular to the load was the most severe stress for both configurations, but the second most severe stress differed for the two configurations. When the load was aligned with the binders' paths, the second most severe type of stress was transverse tension and longitudinal shear within the binders near the region where they traversed through the thickness of the textile. However, when the load was perpendicular to the binders' paths, a severe longitudinal shear stress formed in the wefts.
