“…Therefore, the failure strength in this work is defined as the critical stress at failure initiation (i.e., at initial load drop on the load-displacement response) before the decrease of modulus, and the decrease of modulus is neglected. (5) Shear force component is negligibly small in contrast to the axial force in tensile or compression case for plane woven composites, while the axial force component is negligibly small in comparison with the shear force in pure shear loading case ( Potluri and Thammandra, 2007 ;Naik et al, 2003 ).…”

a b s t r a c tThis paper deals with new analytical solutions to predict tensile and in-plane shear strengths of triaxial weave fabric (TWF) composites accounting for the interaction between angularly interlacing yarns. The triaxial yarns in three directions of 0 °and ±60 °in micromechanical unit cell (UC) are idealized as the curved beams with a path depicted by using sinusoidal shape functions. The tensile and in-plane shear strengths of TWF composites are derived by means of the minimum total complementary potential energy principle founded on micromechanics. In order to validate the new model, the predictions are compared with experimental data in prior literatures. It is shown that the predictions from the new model agree well with experimental results.

This paper reviews the most common formulations to obtain the compression strength of long fiber composites due to fiber buckling. This failure mode was first studied by Rosen (Fibre Composite Materials, pp. 37-45, 1965) who defined two different fiber buckling modes, extensional and transverse. Further studies improved the first model proposed by Rosen by defining with more accuracy the mechanics of the problem. Although each formulation use a different approach to solve the problem, all of them agree in the dependence of fiber buckling on three main parameters: matrix shear strength, fiber initial misalignments and volumetric participation of the fibers in the composite.Once having described the different approaches used, and the parameters on which they depend, this paper describes a new formulation capable of obtaining the compression strength of composites taking into account the fiber buckling phenomenon. This formulation uses the serial/parallel mixing theory developed by Rastellini et al. (Comput. Struct. 86(9):879-896, 2008) to simulate the composite, and takes advantage of knowing the mechanical performance of the composite constituents to simulate the fiber buckling phenomenon. This is done with an homogenization procedure. It consists in introducing the interaction between fibers and matrix into their respective constitutive equations. The interaction between fiber and matrix takes into account fiber initial misalignments, its volumetric participation and the mechanical properties of both constituents.The new formulation proposed is implemented in a finite element code, taking into account that fibers can have different misalignment levels, and that the composite behaves differently if it is under tensile or compression forces. The mechanical performance of the formulation proposed is studied with several finite element simulations of compressed composites. Finally, the correctness of the formulation is proved by comparing the numerical results with the experimental tests provided by Barbero and Tomblin (Int.

“…Fewer geometry characteristic parameters of warp and weft yarns and the elastic moduli of fibre and resin are required to predict tension modulus of PWF composites than with other models given in the literature [5,[14][15][16][17][18][19][20][21][22][23][24][25][26][27].…”

“…They proposed three different models for elastic property prediction, namely, (1) a mosaic model (where fibre continuity and undulation was omitted), (2) a crimp model (where fibre continuity and undulation geometry was described by using trigonometric functions), and (3) a bridging model (with stiffness or compliance averaging in two orthogonal directions and suitable for satin weave composites). Naik et al [5,17,18] considered the fibre undulations in two orthogonal directions and used more detailed trigonometric functions to extend the crimp models of Ishikawa and Chou (i.e., two-dimensional undulation parallel-series and series-parallel models) to evaluate different elastic properties of PWF composites. Saka and Harding [19] and Carey et al [20] developed rectilinear and sinusoidal crimp models to predict elastic properties by means of classical laminate plate theory applied in the context of an elastic foundation and using the principle of equivalent strain energy.…”
