“…Given the complex fibre architecture of textile composites, a promising approach for predicting their fatigue behaviour is multilevel modelling, which allows the inclusion of mesoscale behaviour features in macroscopic descriptions without the need for an a priori postulated macroscopic constitutive law (Carvelli & Poggi, 2001;Edgren, Mattsson, Asp, & Varna, 2004;Tang & Whitcomb, 2003;Zako, Uetsuji, & Kurashiki, 2003). Macroscopic constitutive relations (material properties on the laminate level) are obtained from scaling up material modelling at lower (meso-and micro-) scales where the detailed material structure with its specific material behaviour is represented.…”

“…The basic idea of using periodic boundary conditions is to assume that a part on macro level consists of a number of repeated RUC's in which each basic mechanical element, the RUC, determines the global constitutive law of the material on macro level ( Figure 2) [1, 26,27].…”

Textile fabric reinforced composites are increasingly used in structural applications in the aerospace, automotive and recreational industry. Since experimental testing is labour intensive and time consuming, numerical analysis using Representative Unit Cell (RUC) and Finite Element (FE) analyses for obtaining the elastic material constants have proven to be suitable. One of the drawbacks of the existing techniques is that one is obliged to have identical meshes on opposite faces for applying periodic boundary conditions (PBC), or that multiple part finite element meshes are not allowed. The new ORAS software discussed in this paper allows non-identical meshes at opposite faces and multiple part meshes. If a search is done in the ISI web of knowledge, no papers can be found of the meso-scale finite element modelling with periodic boundary conditions of spread tow fabric composites. With the existing techniques available on the market it is not possible, and therefore the method presented in this paper gives a solution. For the numerical meso-scale FE analysis in combination with macro homogenization for obtaining the macro elastic constants, a thermoplastic carbon-PPS (PolyPhenylene Sulfide) 5-harness satin weave composite (CETEX ® ) was used as an example. The results of the meso-scale FE analysis of the RUC using PBC with macro homogenization obtained with the new technique are in good agreement with those obtained using conventional techniques and experimental data.

“…By applying the 3D PBC, the above mentioned six independent unit load cases are solved. Later, by the application of the volume averaging technique [1,5,24], the homogenized elastic constants of the unit cell are estimated (Table 4). Finally, the elastic constants computed using different boundary conditions are compared to the analytical (method of inclusions [25]) and with the experimental elastic constants ( Table 4).…”

“…In order to estimate the homogenized elastic constants of textile composites using unit cell meso-FE simulations, a numerical procedure is firmly established [1,2]. However, the meso-FE procedure still needs to be improved for analysis of the local stress and damage behavior of the composite using the unit cell FE simulations [3,4].…”

This study forms the second part of a paper on the local damage analysis in a thermoplastic 5-harness satin weave composite under uni-axial static tensile load. The experimental observations of Part I are confronted with the meso-FE simulations. Part II describes the following steps regarding the unit cell meso-FE modeling starting from: 1) Construction of the unit cell geometrical model; 2) Estimation of the homogenized elastic constants of the unit cell using different boundary conditions; 3) Evaluation of the local stress and damage behavior of the unit cell using meso-FE simulations. The aim of the numerical analysis is to investigate the dependency of local ply stress and damage profiles on the adjacent layers of the laminate.
