Abstract

The microscopic mechanical response of composites can provide direct and critical insights for meso- and macro- scale material analyses, and the representative volume element microstructural model is an effective computational medium to virtually characterize and describe the microscale behaviour of the material. This paper presents a comprehensive review of micro-scale mathematical characterizations and demonstrations of unidirectional continuous fibre-reinforced composites. The representative volume element, including its definition and homogenization, is examined in detail. Geometric parameters of the virtual microstructure are analysed, and the microstructure generation algorithms are systematically classified into six categories. Statistical methodologies are introduced to assess the spatial distribution of fibres in the microstructure and explore the structure–property relationships between graphical descriptors and mechanical responses. In addition, defects in the representative volume element microstructure are presented in detail, along with their statistical evaluation methods from different perspectives. A critical discussion of the advantages, differences and limitations of each method (or model) is also provided.

期刊介绍： Composites Part B: Engineering is a journal that publishes impactful research of high quality on composite materials. This research is supported by fundamental mechanics and materials science and engineering approaches. The targeted research can cover a wide range of length scales, ranging from nano to micro and meso, and even to the full product and structure level. The journal specifically focuses on engineering applications that involve high performance composites. These applications can range from low volume and high cost to high volume and low cost composite development. The main goal of the journal is to provide a platform for the prompt publication of original and high quality research. The emphasis is on design, development, modeling, validation, and manufacturing of engineering details and concepts. The journal welcomes both basic research papers and proposals for review articles. Authors are encouraged to address challenges across various application areas. These areas include, but are not limited to, aerospace, automotive, and other surface transportation. The journal also covers energy-related applications, with a focus on renewable energy. Other application areas include infrastructure, off-shore and maritime projects, health care technology, and recreational products.
