Abstract

The Mori-Tanaka method is well-known for its good predictive capabilities and excellent time efficiency. However, a significant weakness of the Mori-Tanaka method is its decreasing accuracy as the volume fraction of particles increases. Therefore, this paper focuses on developing a new approach to improve stiffness predictions for particle-reinforced composites across a wide range of particle volume fractions by using a mixed data-driven and mean-field homogenization modelling strategy. The basic idea is to modify the strain concentration tensor by fitting the results of Mori-Tanaka homogenization to data generated using numerical full-field homogenization based on the representative volume element (RVE). The modified tensor can then replace the original strain concentration tensor within the established framework of Mori-Tanaka homogenization to predict the effective stiffness. The results obtained using the proposed approach are in good agreement with those provided by full-field finite element-based homogenization. Moreover, the results obtained through Mori-Tanaka and double inclusion methods have been added for reference. The presented results demonstrate the potential of the proposed data-driven mean-field model as an efficient approach for addressing the micromechanics of particle-reinforced composites.

期刊介绍： The past few decades have seen outstanding advances in the use of composite materials in structural applications. There can be little doubt that, within engineering circles, composites have revolutionised traditional design concepts and made possible an unparalleled range of new and exciting possibilities as viable materials for construction. Composite Structures, an International Journal, disseminates knowledge between users, manufacturers, designers and researchers involved in structures or structural components manufactured using composite materials. The journal publishes papers which contribute to knowledge in the use of composite materials in engineering structures. Papers deal with design, research and development studies, experimental investigations, theoretical analysis and fabrication techniques relevant to the application of composites in load-bearing components for assemblies, ranging from individual components such as plates and shells to complete composite structures.
