“…Although the fiber undulation and bridging models take into account the undulation of the strand, they are one-dimensional. Naik et al [3,4] have proposed an analytical method to analyze woven fabric composites which consider the undulation of both the strands, actual strand cross-section and weave geometry and the strand fiber volume fraction concept. A 3D finite element analysis was made by Whitecomb [5] and Raju et al [6] to study the properties of woven fabric composites.…”

A micromechanical model for elastic behavior analysis of angle-interlock woven ceramic composites is proposed in this paper. This model takes into account the actual fabric structure by considering the fiber undulation and continuity in space, the cavities between adjacent yarns and the actual cross-section geometry of the yarn. Based on the laminate theory, the elastic properties of 3D angle-interlock woven ceramic composites are predicted. Different numbers of interlaced wefts have almost the same elastic moduli. The thickness of ceramic matrix has little effect on elastic moduli. When the undulation ratio increases longitudinal modulus decreases and the other Young's moduli increase. Good agreement between theoretical predictions and experimental results demonstrates the feasibility of the proposed model in analyzing the elastic properties of 3D angle-interlock woven ceramic composites. The results of this paper verify the fact that the method of analyzing polyester matrix composites is suitable for woven ceramic composites.

These models represented the woven geometry using two layers of yarns with homogenized properties for each layer considering the effects of yarn undulation.…”

This study introduces a unit cell (UC) based finite element (FE) micromechanical model that accounts for correct post cure fabric geometry, in-situ material properties and void content within the composite to accurately predict the effective elastic orthotropic properties of 8-harness satin weave glass fiber reinforced phenolic (GFRP) composites. The micromechanical model utilizes a correct post cure internal architecture of weave, which was obtained through X-ray microtomography (XMT) tests. Moreover, it utilizes an analytical expression to up-date the input material properties to account for in-situ effects of resin distribution within yarn (the yarn volume fraction) and void content on yarn and matrix properties. This is generally not considered in modeling approaches available in literature and in particular, it has not been demonstrated before for FE micromechanics models of 8-harness satin weave composites. The UC method is used to obtain the effective responses by applying periodic boundary conditions.The outcome of the analysis based on the proposed model is validated through experiments.After validation, the micromechanical model was further utilized to predict the unknown effective properties of the same composite.

“…Several models addressing the mechanical behaviour of such structures are reported in literature. Models based on the classical laminate theory (CLT) [1][2][3] are widely used for wavy structures. However, these models present shortcoming for predictions of transverse moduli, E 33 , and G 13.…”

OATAO is an open access repository that collects the work of Toulouse researchers and makes it freely available over the web where possible. AbstractIn this paper, experimental, analytical and numerical analysis are used to study and model the mechanical behaviour of a heat exchanger core consisting of a 3D-periodic structure. The purpose of the present investigation is not only to acquire knowledge on the mechanical behaviour of a given heat exchanger core but also to propose a simplified approach to model this behaviour. An experimental study is carried out in order to get an insight on the mechanical behaviour of this structure. Global static characteristics are obtained via analytical and finite element analysis of a unit cell of the core. Dynamic behaviour is studied by means of finite element calculations based on the results of the static modelling.The proposed approach is validated by comparison with experimental tests results.
