Journal Francophone de Tribologie

O Journal Francophone de Tribologie (JFT) é uma revista arbitrada fundada em 2026, publicada pelo Grupo Científico e Técnico (GST) de Tribologia da Associação Francesa de Mecânica. A revista destaca, de forma contínua, contribuições significativas — teóricas, numéricas e experimentais — no campo da tribologia e disciplinas relacionadas, dentro de uma abordagem de difusão aberta da pesquisa científica francófona.
A revista JFT valoriza a publicação de artigos científicos em língua francesa, embora também sejam bem-vindas submissões em língua inglesa. Todos os anos, uma edição especial reúne os artigos derivados das apresentações realizadas nas Journées Internationales Francophones de Tribologie do ano.

Adaptive FEM-DEM bridging coupling for third-body evolution in sheared granular media

The frictional behavior of dry solids in sliding contact is significantly affected by the formation and accumulation of wear particles at the interface. These particles create an amorphous layer known as the third body, which undergoes intense deformation. We show that accurately capturing the evolution of the third body requires a precise modeling of the physical dimensions of the surrounding elastic bodies and boundary conditions. This implies that a computational tribology simulation engine must resolve both the fine-scale dynamics of wear particles and the large-scale structural dimensions of the sliding bodies. To address this challenge, we employ a coupled Finite Element Method (FEM) and Discrete Element Method (DEM) approach. The DEM is used to model the third body, where grain-scale discretization is crucial, while the FEM represents the first bodies as a continuum, reducing computational cost. The coupling between FEM and DEM is achieved using the bridging method. To allow unrestricted growth of the third body beyond the initial discrete region, we implement an adaptive coupling mechanism that enables FEM regions to transition into DEM regions. This transition occurs when a predefined criterion is met, based on the average change in neighboring particles. Our approach is validated for both amorphous materials and ordered crystalline lattices. Finally, as a proof of concept, we apply the adaptive coupling framework to simulate the evolution of a third body initially composed of stiff elliptical particles.

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.
