“…Application of CZM requires a-priori knowledge of an intended crack path and a use of cohesive elements. Another theory to evaluate intra-laminar failure was continuum damage mechanics (CDM) (Camanho et al 2003;Heinrich et al 2013). In CDM, damage is described by introducing internal state variables (D ij ) into an algorithm of continuum mechanics to represent micro defects in a damage process in the material.…”

Composites reinforced with woven or braided textiles exhibit high structural stability and excellent damage tolerance thanks to yarn interlacing. With their high stiffness-to-weight and strength-to-weight ratios, braided composites are attractive for aerospace and automotive components as well as sports protective equipment. In these potential applications, components are typically subjected to multi-directional static, impact and fatigue loadings. To enhance material analysis and design for such applications, understanding mechanical behaviour of braided composites and development of predictive capabilities becomes crucial. Significant progress has been made in recent years in development of new modelling techniques allowing elucidation of static and dynamic responses of braided composites. However, because of their unique interlacing geometric structure and complicated failure modes, prediction of damage initiation and its evolution in components is still a challenge. Therefore, a comprehensive literature analysis is presented in this work focused on a review of the state-of-the-art progressive damage analysis of braided composites with finite-element simulations. Recently models employed in the studies on mechanical behaviour, impact response and fatigue analyses of braided composites are presented systematically. This review highlights the importance, advantages and limitations of as-applied failure criteria and damage evolution laws for yarns and composite unit cells. In addition, this work provides a good reference for future research on FE simulations of braided composites.

“…In the 3D orthogonal woven composite, only two components exist: fiber and resin. Part of the resin is filled in the fiber yarns (warp yarns, weft yarns and Z yarns) to form matrix impregnated fiber yarns (Heinrich et al, 2013). Another part fills the spaces between the matrix impregnated fiber yarns.…”

We proposed a multi-scale structure modeling scheme to analyze the damage behaviors of three-dimensional orthogonal woven composite materials subject to quasi-static and high strain rate compressions. The multi-scale structure model includes: (1) micro/meso/macro structure model with periodic boundary conditions for homogenizing the heterogeneous fiber/resin system into unit cells, and (2) a macroscopic rate dependent plasticity model combined with critical damage area failure theory that accounts for the compressive deformation and failure strength of the composite material. The numerical results from the multi-scale structure model provide the locations of stress propagation and the progressive failure behavior within the 3D orthogonal woven composite material. The multi-scale model and the numerical simulation results are validated using compression test results at the strain rate range from 0.001 to 2100/s. The methodology we proposed could be applied to understand the microstructure damage mechanisms of 3-D textile composite materials from meso-and macro-structure level in simpler geometrical model and easier design approaches.

“…The presence of fibers introduces a non-uniform temperature distribution on the surrounding matrix during curing, resulting in residual stresses that cause the material to behave differently from a bulk matrix that is cured without fibers. Modeling the generation of heat and stresses during curing and the effect on the resulting cured material properties are presented in Heinrich et al (2012Heinrich et al ( , 2013. Alternatively, the effect of curing can be accounted for by modeling the matrix using an effective stress-strain response that is directly obtained from a cured composite specimen rather than a bulk pure matrix material.…”

Keywords:Hybrid 3D textile composite Flexure Kink banding Progressive damage and failure a b s t r a c t This paper presents an experimental investigation of the deformation responses and failure mechanisms of hybrid 3D textile composites (H3DTCs) subjected to quasi-static three-point bending. The term ''hybrid" refers to different constituent fiber tows, including carbon, glass, and Kevlar that are integrally woven into a single preform. Three different hybrid architectures, manufactured by varying the percentages and lay-ups of the constituent fiber tows, were examined to understand the effect of hybridization on the resulting performance enhancement, including the bending modulus, flexural yield stress, and strain to failure. All the architectures show a ''plastic-like" nonlinear flexural response, indicating considerable damage tolerance and durability for this class of materials. It has been found that increasing the thickness of the specimens can increase the strain to failure in flexure. For an asymmetric H3DTC, which refers to an architecture that has carbon plies on one side and glass plies on the other (through-thethickness), an increased flexural yield stress can be achieved by placing the glass on the side that experiences compressive straining in flexure, whereas the failure strain is reduced by placing the carbon on the side which experiences tension. Distributed matrix cracking was observed in regions of predominant tension through a digital image correlation (DIC) technique. Although the experimental results show architecture-dependent responses, fiber tow kinking, which develops on the compressive side of the specimen is determined to be a strength limiting mechanism for this class of materials subjected to flexural loading. The experimental results are subsequently used as a basis for developing a mechanics based multiscale computational model for H3DTC deformation, damage and failure response in flexure. Details of the modeling strategy and the development of damage and failure constitutive models are presented in Part II of this two-part sequence (Zhang et al., in press).
