“…Figure 22 shows the deformed fabric model. The fabric edge deformation shown is consistent with dome compaction results for 0 o -90 o 2D fabric given in references [19,44]. Figure 23 shows the yarn paths on the dome inside and through thickness cross sections at a selected location.…”

“…The dome forming problem has been widely addressed in literature for 2D fabrics with several analytical and experimental results available [19,23,44,[47][48][49][50][51]. A fabric model with an in-plane dimension of 360 mm in the warp direction and 300 mm in the weft direction was built.…”

A multi-scale approach to modelling is optimal for computationally intensive problems of a hierarchical nature such as 3D woven composites. In this paper an approach capable of modelling feature/component scale fabric deformations and defects is proposed. The proposed technique starts with a meso-scale model for predicting the as-woven geometry of a single unit cell using a high fidelity digital element method. The unit cell geometry is then converted into a macro-scale fabric model by geometric reduction then tessellation. On the macro-scale, two and three dimensional approaches to yarn geometry representation are proposed, with an accompanying yarn mechanical model. Each approach is evaluated based on solution accuracy and computational efficiency. The proposed approach is then verified against experimental results on the meso and macro scales. The applicability of this modelling technique to larger scale compaction problems is then investigated. The proposed algorithm was found to be accurate and computationally efficient.

“…Nevertheless, the energy required to deform woven composite fabrics can be approximately treated as the strain energy of the corresponding deformation status in our hyperelastic approach during forming process, provided that the unloading process is not considered. Similar treatment is implied in the development of hypoelastic models for woven composite fabrics [4,5]. Therefore, the fiber reinforced constitutive framework in Section 2 is applicable to woven composite fabrics.…”

“…Nevertheless, it requires lengthy computational time [3]. A number of researchers have developed hypoelastic constitutive models for characterizing the behavior of woven composite fabrics at large strain [4,5]. Based on an objective derivative，it shows that using the fiber rotation allows to keep the orthotropic direction coinciding with the fiber direction.…”

A Simple Anisotropic Fiber Reinforced Hyperelastic Constitutive Model for Woven Composite Fabrics

et al. 2010

Based on fiber reinforced continuum mechanics theory, a simple hyperelastic constitutive model is developed to characterize the anisotropic nonlinear material behaviour of woven composite fabrics under large deformation during forming. The strain energy function for the hyperelastic model is additively decomposed into two parts nominally representing the tensile energy from weft and warp yarn fiber stretches and shearing energy from fiberfiber interaction between weft and warp yarns, respectively. The proposed material characterization approach is demonstrated on a balanced plain weave composite fabric. The equivalent material parameters in the hyperelastic constitutive model are obtained by matching experimental load-displacement data of uni-axial tensile and picture frame tests on the woven composite fabric. The development of this anisotropic fiber reinforced hyperelastic model is critical to the numerical simulation and optimization of woven composites forming.
