Abstract

Inclined honeycomb structures have garnered significant attention due to their exceptional mechanical properties, including enhanced strength-to-weight ratios and improved energy absorption capabilities. This comprehensive review aims to provide a deeper understanding of the complex mechanics governing these structures, shedding light on potential applications in aerospace, biomedical, and energy sectors. The significance of inclined cells in honeycomb structures is examined, highlighting their mechanical properties and the effects of cell geometry and material properties on their behavior. Analytical and numerical models are reviewed, revealing the impact of inclined cell angles on mechanical performance. Optimal cell angles for enhanced mechanical properties are identified, along with stress distribution and failure mechanisms. The influence of cell wall thickness, material properties, and honeycomb structure configurations on mechanical behavior is investigated. Cell shape variations and design optimization strategies for inclined honeycomb structures are also addressed, emphasizing the importance of geometrical parameters and material selection. The crucial findings indicate that inclined honeycomb structures exhibit improved mechanical properties compared to traditional honeycombs, including increased compressive strength and toughness. Still, challenges persist, including manufacturing complexities and limited understanding of failure mechanisms. This review synthesizes existing knowledge, identifies knowledge gaps, and outlines future research directions. Theoretical models are compared with experimental data, highlighting areas for improvement. By advancing research and overcoming existing challenges, inclined honeycomb structures can be optimized for various high-performance applications, such as aerospace engineering, biomedical devices, energy absorption systems, automotive components, and advanced composite materials. Ultimately, unlocking the potential of these structures holds promise for revolutionary innovations across multiple industries. Researchers, engineers, and industry professionals will benefit from this comprehensive analysis, enabling the development of optimized inclined honeycomb structures for various applications.
