Modelling of composite materials energy by fiber bundle model

The European Physical Journal Applied Physics (2020)

S. Boufass A. Hader M. Tanasehte H. Sbiaai I. Achik

In this paper, the fiber energy in composite materials, subject to an external constant load, is studied. The investigation is done in the framework of fiber bundle model with randomly oriented fibers. The charge transfer is done only between neighboring close fibers according to the local load sharing. During the breaking process, the fibers expand, increasing their elastic energy, but when the fiber breaks, it loses its link with its neighboring fibers reducing the cohesive energy of the materials. The results show that the material energy presents one maximal peak at cross over time which decreases linearly with the applied force and scales with the lifetime of the material. However, the temperature does not have a remarkable effect on the material energy variation. In addition, the link density fiber decreases exponentially with time. The characteristic time of the obtained profile decreases with the applied force. Moreover, this density decreases with applied forces according to the Lorentz law with a remarkable change at critical force value.

Scaling law in avalanche breaking of composite materials

Multidiscipline Modeling in Materials and Structures (2020)

A. Hader H. Sbiaai M. Tanasehte L. Amallah Y. Boughaleb

Purpose The fibers are loaded by the cosine component of the external load, when a fiber fails, and due to the local load-sharing nature, its force is shared by surviving neighboring fibers. The results show that the system presents a greater resistance and toughness toward the applied load compared to the classical one. Design/methodology/approach In this paper, the authors adopt the dynamics of a local load-sharing fiber bundle model in two dimensions under an external load to study scaling law in failure process of composite materials with randomly oriented fibers. The model is based on the fiber bundle model where the fibers are randomly oriented. The system is different to the classical one where the fibers are arranged in parallel with the applied load direction. Findings The evolution time of the fraction of broken fiber is described by an exponential law with two characteristic times. The latter decrease linearly and exponentially respectively with both applied load and temperature. Originality/value Scaling behavior of the broken fiber numbers with the size system shows that the system exhibits a scaling law of Family–Vicsek model with universal exponents.

The effect of fibers-matrix interaction on the composite materials elongation

IOP Conference Series Materials Science and Engineering (2020)

M. Tanasehte A. Hader H. Sbiaai I. Achik Y. Boughaleb

Abstract Failure process in composite materials is the basis of various actual researches. It study is the almost treated with fiber bundle model (FBM), in the framework of local load sharing rule (LLS), were the breakdown mechanisms is controlled by different parameters. Almost tentative investigates only fiber failure process and neglects the effect of the matrix, as a second crucial component of composite. Effectively, quantification of fibers-matrix interactions is not generally clear. Furthermore, the diversity of composite intrinsic proprieties complicates this quantification. The originality of our investigations is to quantify all interactions between fibers and matrix in a single parameter. Likewise, this latter gives us a different results than the ones obtained with FBM where the interaction amplitude is neglected. Moreover, interaction decelerates the failure process; it subdivides the avalanche phenomena on two consecutive regimes separated by delaying duration. These results are more similar to the ones obtained regular fibers substations. Therefore any fiber have its own elongation, the mean fiber elongation produces an elastic energy. The temporal variation of these latter presents two extremum separated by time duration; at this separated period, the material self-rearranging. These results are more similar to the ones obtained by the regular fibers substitution process.

Crack diffusion in failure process of composite materials

Molecular Crystals and Liquid Crystals (2016)

A. Hader I. Achik H. Sbiaai R. Bakir Y. Boughaleb

We study the crack diffusion in composite materials subject to a local load-sharing fiber bundle model in two dimensions under an external load applied at a single point. By the use of the local load-sharing rule, the redistributed load remains localized along the boundary of the broken patch. We investigated the correlation function of the broken fibers. The results show that this magnitude decreases exponentially with time and it's characterized by a characteristic time which is inversely proportional to the diffusion coefficient of the localized crack. The results exhibit also that the crack correlation function in the failure process in composite materials decreases with both of applied load and temperature. We calculate then the diffusion coefficient of the localized crack. We have found that this diffusion coefficient increases by power law with the applied load and thermal noise.
