Abstract

As a representative class of mechanical metamaterials, lattice structures have emerged as a frontier research focus due to their tailorable unit cell topologies and exceptional mechanical properties. In recent years, bio-inspired design approaches, informed by the multiscale structural features of biological systems, have provided innovative pathways for optimizing performance and enabling functional innovations in lattice structures. Leveraging the unique capabilities of additive manufacturing, bio-inspired lattice structures demonstrate significant potential in lightweight design, energy absorption, and mechanical property modulation. This review systematically summarizes recent advances in bio-inspired lattice structures and establishes a multidimensional classification framework based on bio-inspired design methodologies. First, design strategies are categorized into two hierarchical levels: unit cell-scale bio-inspired designs and macroscopic lattice architectures. Second, a taxonomy rooted in biological prototypes is proposed, encompassing plant-dominated, animal-dominated, and multi-source bio-inspired fusion designs, accompanied by systematic comparative analyses. Furthermore, advanced fabrication techniques for lattice structures are comprehensively discussed, and scientifically grounded perspectives on future development directions are presented. This work provides theoretical guidance and technical references for the design and high-performance development of novel bio-inspired lattice structures.

期刊介绍： Thin-walled structures comprises an important and growing proportion of engineering construction with areas of application becoming increasingly diverse, ranging from aircraft, bridges, ships and oil rigs to storage vessels, industrial buildings and warehouses. Many factors, including cost and weight economy, new materials and processes and the growth of powerful methods of analysis have contributed to this growth, and led to the need for a journal which concentrates specifically on structures in which problems arise due to the thinness of the walls. This field includes cold– formed sections, plate and shell structures, reinforced plastics structures and aluminium structures, and is of importance in many branches of engineering. The primary criterion for consideration of papers in Thin–Walled Structures is that they must be concerned with thin–walled structures or the basic problems inherent in thin–walled structures. Provided this criterion is satisfied no restriction is placed on the type of construction, material or field of application. Papers on theory, experiment, design, etc., are published and it is expected that many papers will contain aspects of all three.
