“…The results in Ref. 33 indicate that the mechanical behaviors of composites are closely dependent on the fiber packing arrangements. For discussing the fiber packing arrangement influences on the failure strength of composites, three different fiber arrangements, that is square edge packing ( Fig.…”

In this study, an isoparametric micro‐mechanical model is developed to study the failure behaviors under biaxial loadings for composites with different fiber arrangements. For validating the method, the numerical results of the unidirectional (UD) composite lamina with consideration of two different failure criteria (the constituent failure criterion and UD failure criterion) are compared with the experimental results. On this basis, the fiber arrangements and fiber off‐axis angles influence on the failure envelopes for the UD composite lamina are studied. Furthermore, the failure strength of a typical composite laminates is also investigated. The results show that the failure strength of composite laminates is closely dependent on the fiber arrangements. Compared with the hexagonal packing, the square diagonal packing provides the higher failure strengths. POLYM. COMPOS., 38:2734–2742, 2017. © 2015 Society of Plastics Engineers

This article presents a numerical technique for computing the biaxial yield surface of polymer-matrix composites with a given microstructure. Generalized Method of Cells in combination with an Improved Bodner-Partom Viscoplastic model is used to compute the inelastic deformation. The validation of presented model is proved by a fiber Bragg gratings (FBGs) strain test system through uniaxial testing under two different strain rate conditions. On this basis, the manufacturing process thermal residual stress and strain rate effect on the biaxial yield surface of composites are considered. The results show that the effect of thermal residual stress on the biaxial yield response is closely dependent on loading conditions. Moreover, biaxial yield strength tends to increase with the increasing strain rate.

The primary goal of this paper is to investigate the combined effects of strain rate and microscopic parameters (fiber off-axis orientation, array pattern and cross-sectional shape) on the mechanical behavior of metal matrix composites (MMCs). To this end, a ratedependent micromechanical model by the combination of finite-volume theory and Bodner-Partom viscoplastic model is developed to analyze the inelastic response of MMCs. In the simulations, the fibers are modeled as linearly elastic while the metal matrix exhibits viscoplasticity. The macroscopic stress-strain response, local stress and strain fields are obtained simultaneously. An acceptable agreement has been found between the model's prediction and finite-element results, which demonstrates the good predictive capabilities of the proposed method. It is concluded that the composite response is strongly affected by strain rate, fiber array pattern and cross-sectional shape in the elastic-plastic region but to a lesser extent in the elastic region. Furthermore, the clustering array provides stiffer response than random and square ones; the square fiber predicts stiffer response than circular and elliptical ones. However, increasing the strain rate will weaken the influence of clustering array and square fibers.
