This study introduces an analytical micromechanical model considering progressive damage designed to predict the elastic and strength properties of plain weave composites subjected to fatigue loading. The presented model is composed of a multi-scale micromechanical model, wherein a progressive damage mechanism has been incorporated. During the development of this multi-scale micromechanical model, a representative volume element was chosen and homogenized, utilizing assumptions pertaining to identical out-of-plane stresses and in-plane strains. These assumptions satisfy the conditions of equilibrium and displacement continuity in the representative volume element and, through a three-step process, enhance the model’s accuracy in applying the damage model and predicting the elastic properties of plain weave composites under static loading. Subsequently, the damage mechanism was progressively developed by accounting for the crucial role of matrix crack growth. This was achieved by employing the kinetic theory of fracture for polymers and integrating it with the multi-scale micromechanical model. Ultimately, the elastic and strength properties of plain weave composites under fatigue loading were predicted. A comparison of the results derived from the present model with those available in the literature demonstrated a high degree of agreement.

A micromechanical model is implemented to indicate the progressive fatigue problem of a laminated composite with a central circular hole under fatigue loading based on a finite element model. The mechanical properties of the composite lamina are represented based on the characteristics of the fiber and the matrix through a micromechanics model. An appropriate algorithm is then adopted to simulate fatigue damage development in the composite lamina. According to this algorithm, the stress field of the composite subjected to fatigue load is initially obtained using the finite element method. Finally, the predicted results of the stresses in the constituents i.e. fiber and matrix are determined according to the micromechanical bridging model. Finally applying proper damage driving relations leads to damage degree in each element. The proposed model is proven to be successful in the observation of the fatigue behavior with stiffness degradation in each element of the composite in each cycle. Results are reported and validated using those micromechanical models and experimental data available in the literature.

The design process of laminated composites faces two challenges: the engineer designs the product and its morphology, but also, simultaneously, the material. The number of design solutions can be huge since the solution space is very large. Standard CAE systems (CAD, Finite Element Simulation) do not offer to the designer an approach to explore design spaces easily handling design parameters that are intrinsic to the laminate structures: number of plies, layers' constitutive laws, viscoelastic capacity of the matrix and volume fraction of fibers. This paper provides a new model of behavior making explicit these design parameters. This Parametric and reduced Behavior Model (PRBM) allows engineers to make rapid simulations of the product they are creating. Integrated in a meta-model of Knowledge, it is combined to usual specific knowledge that are typically the domain of composite experts and manufacturing experts. Our PRBM is made from a separated numerical method, next enabling (1) a multiscale approach: the engineer can implement reasoning either at the scale of the fiber, or at the scale of the ply, at the scale of the plies interfaces, at the scale of the lamination or at the scale of the structure, or, (2) a multiphysical approach: the engineer can independently manage the mechanical effect of each ply and each interface, either in static or dynamic cases; in the latter, the creeping behavior can be considered. Two simple cases are presented to illustrate the relevance of the PRBM when simulating composite structures: one under a static load and the having a dynamic behavior.Keywords Separated behavior model .
