Abstract:
Topological interlocking structures have garnered significant attention for their distinctive properties, including robust
resistance to crack propagation, outstanding energy absorption, adaptable flexibility, high resistance to missing
elements and easy assembly and disassembly. Moreover, integrating various materials into a single structure enables
versatile design possibilities. This paper comprehensively reviews recent research on topological interlocking
elements and structures, encompassing element designs, manufacturing techniques and engineering applications.
Furthermore, it explores the performance of topological interlocking structures, covering aspects such as fracture
resistance, structural integrity, bending flexibility, ease of assembly and disassembly and energy absorption. While
topological interlocking elements offer various benefits, challenges remain in their broader implementation,
particularly as structural members in civil engineering structures. This paper engages in a critical discussion of existing
research gaps and outlines directions for future research.
