Meso-level textile composites simulations: Open data exchange and scripting

Abstract

The article presents a user interface for modelling of textile composites, which combines open XML input and output formats with scripting for definitions of the reinforcement models under (local) shear, tension and compression deformations. The open input format (parameters of the textile reinforcement) allows easy integration of a meso-level (unit cell) textile processor upstream – with, for example, textile process modelling software or forming models, which define local parameters of the textile reinforcement. The scripting command format makes possible automated processing of the information on local reinforcement deformation conditions, and offers itself to be integrated in user software without accessing or knowing internal computational procedures or native data formats of meso-level textile processor. The open output format allows transferring the results of the meso-level textile processor downstream to meso-level models of the micromechanics or the permeability of a textile composite unit cell. These results can be further streamed to allow macro-level structural, forming or impregnation analysis. The integration approach is illustrated for meso-level textile processor – WiseTex software, integrated with processing of digital images and calculations of the fabric permeability tensor, micromechanics models and meso-level finite element ABAQUS model.

Full-field strain measurements and meso-FE modelling of hybrid carbon/self-reinforced polypropylene

“…The geometric model of the reinforcement was built using the WiseTex software [36,37]. The input data was acquired using measurements of the reinforcement geometry and is shown in Table 1.…”

“…The stiffness and strength as well as strain patterns are obtained from tensile tests combined with DIC. The geometry of the complex weave architecture of SRPP/CFRPP is measured and converted into a geometric unit cell model by WiseTex [36,37]. This geometry is then meshed and modelled using the embedded element method in Abaqus.…”

Fatigue testing and online inspection of carbon textile composites for aeronautical applications

“…The required unit cell geometrical model was constructed using 'WiseTex' software based on the measured micro-CT data from the satin weave composite (Lomov et al, 2014;Verpoest & Lomov, 2005). From the reconstructed images, the textile information required for the construction of the RUC geometry, such as the spacing (distance between two warp or weft yarn heart lines), width and thickness of the yarns, was measured at 20 different locations in both warp and weft yarn directions.…”

From a Virtual Textile to a Virtual Woven Composite

“…Meso-level (unit cell) modelling of textile composites is an established field, with a plethora of works published, and in-house, commercial and open source software tools available, for example, WiseTex [1,2] and TexGen [3]. A meso-level textile processor (MLTP) can be defined as a numerical tool, which:…”
