On the constitutive modelling and damage behaviour of plain woven textile composite

A multiscale homogenization iterative algorithm of 2D orthogonal prepreg carbon/aramid/epoxy woven-ply

“…These parameters are all For the purpose of facilitating multiscale numerical method of tensile specimens, RUC and ECPL-cell are respective selected as the minimum periodic unit in macroscale (Figure 2). However, ECPL-cell can be viewed as a simplified structure of RUC proposed in Ref., [28][29][30]33 which will greatly reduce the homogenization calculation from mesoscale to macroscale with the premise of ensuring adequate calculation accuracy. The sizes of these two structures are inconsistent, the specific sizes and corresponding values are depicted in Figure 3 and Table 1.…”

“…Nevertheless, it is regrettable that this simple superposition is confirmed numerically tedious and expensive. Therefore, the popular equivalent cross-ply laminate (ECPL) cell [28][29][30] is currently employed by researchers for mesoscale to macroscale homogenization. Because ECPL removes profile information of yarns, such as the curvature, weaving path, and crosssection of the yarn in RUC, and adopts a specific homogenization method, the numerical model can be greatly simplified, thereby deeply reducing the computing time and modeling cost of macroscopic composite architectures.…”

“…28 describes the damage initiation and evolution of the mesoscale model with low-velocity impact 31,32 loading conditions of plain weave composite models characterized by ECPL. The work of Mulay and Udhayaraman 29,30 studied the mesoscale failure modes of plain weave textile composite (PWTC) in mesoscale with the ECPL, and generalized the M-T failure theory into ECPL. In addition, Hou et al 33 adopted ECPL combined with the classical laminate theory and M-T theory, the progressive damage failure of adhesive laminate is studied.…”

Numerical and experimental investigation on the load‐bearing performance of plain‐woven composites hybrid bonded‐bolted joints

“…33 The standard tensile specimens of HBB joints were prepared for experiments, and the quasi-static uniaxial tensile displacement loads were employed. For simulation, an equivalent cross-ply laminate (ECPL) structure capable of representing the woven structures of fiber bundles was introduced using the multiscale modeling approach of Udhayaraman and Mulay 34 and Mulay and Udhayaraman 35 to build the finite element models of HBB joints. Loadbearing performance and damage modes were compared between experiment and simulation based on the 3D Hashin failure criterion and the cohesive mechanical model.…”

Tensile Behaviour of Fabric Reinforced Plies

“…It is natural to form composites (of all kinds) to solve one issue but the tendency to multi-functionalize the materials requires more attention on how the components of the composites really interact. There are many studies regarding, for instance, the composite laminates mechanical properties (both empirical and theoretical) [1-10] but they are just few studies regarding the fabric reinforced laminates (or layered fabric reinforced polymers) even if creating various stacking sequences of various fabric it could be possible to solve more than one mechanical property [11][12][13][14][15][16][17][18]. Also the use of hybrid fabrics (made of combinations of the three above mentioned types of artificial fibers) could be used to get better mechanical properties of materials with some difficulties generated by the different quality of interphase.…”
