“…The observed experimental evidence will motivate the further development of mathematical and numerical models for considered fabric to include damage onset and development. The reader will find interesting, and relevant, experimental investigation involving fiber reinforcements for composites in the papers, [46,47,[73][74][75][76] where also once set and progress of damaged is considered. In future investigations, the methods there used will be adapted to the present contest.…”

“…Among the variety of papers dealing with modeling of effective mechanical properties of composites and their experimental verification, the following group of papers in which a coupling between the topology of fibrous reinforcement (or particle) reinforcement and material symmetry of constitutive model describing composite can be distinguished, for instance: Sun and Vaidya [30], Gan et al [9], Liu et al [19], Würkner et al [37], Selvadurai and Nikopour [28] and others.…”

Mechanics of composite materials was in the last decade one of the most rapidly explored engineering area, basically due to huge progress in composite fabrication and use. The main problem referred in this chapter is how to correctly predict averaged effective properties by implementation of numerous homogenization techniques. Useful classification of composites with respect to the format of effective stiffness matrix, based on the analogy between the crystal lattice symmetry and respective configuration of reinforcement in the RUC, is given. Extended section is focused on conventionally used Hill's theorem on upper and lower bounds by Voigt and Reuss' isotropic estimation for approximate determination of stiffness and compliance matrices of anisotropic composite. Consistent application of the Hill theorem to the elements of elastic stiffness or compliance matrices (but not to engineering anisotropy constants) enable to explain some peculiarities of the Poisson ratio diagrams, met in respective bibliography (e.g., Aboudi et al., Micromechanics of Composite Materials, 2013; Sun and Vaidya, Compos. Sci. Technol. 56:171-179, 1996; Gan et al., Int. J. Solids Struct. 37:5097-5122, 2000). The new effective proposal to achieve approximation of the mechanical modules of unidirectionally reinforced composites by the use of hybrid-type rule of weighted average between the Voigt and Reuss upper and lower estimates is proposed. Capability of this averaged interpolation was checked based on selected findings by Gan et al. (Int. J. Solids Struct. 37:5097-5122, 2000) for Boron/Al composite, which show good convergence and enable to treat weighting coefficients as universal ones over the full V f range.

“…Besides, an elasticity approach towards the evaluation of the transverse modulus of unidirectional fibrous composites, with the concurrent consideration of an irregular distribution of fibers, was made in [18], while Shah et al [19] proposed a detailed analysis on the compressive properties of fibrous composites of a polymeric matrix via combined end and shear loading.…”

Abstract:In this paper, a geometric body-centered model to simulate the periodic structure of unidirectional fibrous composites is presented. To this end, three prescribed configurations are introduced to predict in a deterministic manner the arrangement of internal and neighboring fibers inside the matrix. Thus, three different representative volume elements (RVEs) are established. Furthermore, the concept of the interphase has been taken into account, stating that each individual fiber is encircled by a thin layer of variable thermomechanical properties. Next, these three unit cells are transformed in a unified manner to a coaxial multilayer cylinder model. This advanced model includes the influence of fiber contiguity in parallel with the interphase concept on the thermomechanical properties of the overall material. Then, by the use of this model, the authors propose explicit expressions to evaluate the longitudinal and transverse thermal conductivity of this type of composite. The theoretical predictions were compared with experimental results, as well as with theoretical values yielded by some reliable formulae derived from other workers, and a reasonable agreement was found.
