JFT

Journal Francophone de Tribologie

The Journal Francophone de Tribologie (JFT) is a peer-reviewed journal founded in 2026, published by the Tribology Scientific and Technical Group of the French Society of Mechanics. The journal publishes significant contributions—whether theoretical, computational or experimental—in the field of tribology and related disciplines, with a view to promoting the open dissemination of francophone scientific research. The JFT journal encourages the dissemination of scientific articles in French; however, submissions in English are also welcome. Each year, a special issue brings together the papers presented at the annual conference Journées Internationales Francophones de Tribologie.

Fracture Toughness of Periodic Beam Lattices

The study tackles the challenge of accurately modeling fracture behavior in beam lattices, which is essential for designing robust architected materials. Our research focuses on evaluating how the lattice's microstructure and material properties affect fracture toughness. We employed finite element simulations based on the Euler-Bernoulli beam theory to investigate crack propagation, using a failure criterion that initiates beam fracture when maximum axial stress exceeds critical strength. Building on observations from these simulations, we developed a multi-phase-field fracture model with Cosserat elasticity to integrate consistent toughness characteristics into a comprehensive framework for lattice design. This model was validated through experimental tests, ensuring a close match between theoretical predictions and physical reality. Our findings reveal that the energy release rate remains relatively stable during crack propagation, underscoring its reliability as a measure of the toughness of periodic lattice structures. We discovered that toughness is predominantly influenced by beam height and material properties such as tensile strength and Young's modulus, while slenderness has minimal impact. Additionally, cracks were observed to preferentially propagate along the lattice's structural directions due to stress localization effects, highlighting the importance of the microstructure in fracture behavior. The implications of this research are significant, suggesting that improved modeling of fracture in lattice structures can enhance material design reliability and optimization. This study bridges the gap between theoretical models and real-world applications, providing valuable insights for the development of advanced materials with tailored fracture properties.

Numerical estimation and optimization of the fracture toughness in short-fibre ceramic matrix composites

Achieving greater engine efficiency by increasing gas temperatures is a key challenge set by the European Commission for the aerospace industry by 2050. However, traditional metal alloys may fail under such extreme conditions. Ceramic matrix composites (CMCs) have emerged as a promising alternative, particularly short-fiber CMCs, which offer enhanced performance in components with complex geometries. This paper presents a novel computational framework to predict the fracture toughness of short-fiber CMCs based on the Coupled Criterion approach. The influence of various composite parameters has been systematically analyzed and validated against existing experimental data, demonstrating the model's reliability and potential as a robust design tool for next-generation aerospace applications.
