High dissipation of impact and vibration energy, vibration-assisted self-healing, high tolerance to block failure and an ease of assembly/disassembly make topological interlocking structures ideal for safety barriers, protective shields and floating structures. The theory of these phenomena will open a way for more efficient protection of infrastructure against both natural and human perpetrated impacts and for developing new methodology in constructing mobile marine bases. This constitutes the main benefit of the project. Furthermore, understanding the resonance structure of travelling waves will improve methods of non-destructive monitoring by back analysing spectral signatures of the waves.

冲击和振动能量的高耗散、振动辅助的自我修复、对块故障的高耐受性以及易于组装/拆卸使得拓扑互锁结构成为安全屏障、防护罩和浮动结构的理想选择。这些现象的理论将为更有效地保护基础设施免受自然和人为的影响以及开发建造移动的海洋基地的新方法开辟一条道路。这是该项目的主要好处。此外，了解行波的共振结构将通过反分析波的频谱特征来改进非破坏性监测的方法。
