The CI and his international collaborator have recently proposed a new principle of design of materials and structures based on topological interlocking of constituent elements. Elements of simple shape, such as tetrahedra, are assembled in structures that keep their integrity without any binder or connectors. Unusual properties, such as high fracture toughness and damage tolerance were found. The project aims at investigating the mechanical and acoustic properties of the newly discovered interlockable geometries (cubes, octahedra, dodecahedra and icosahedra) and identifying the areas of application. The project will promote the international leading role of the collaborating institutions in this novel field.Read moreRead less

The project aims to develop a new concept in materials design based on assemblies of interlocked elements. Interlocking is achieved topologically by special arrangements of blocks without connectors. Such assemblies can form structures possessing special mechanical properties and serve as load-bearing skeletons in composites with a binder phase providing desired functional properties. Various types of interlocked assemblies will be modelled, produced and tested to determine their mechanical and acoustic properties. A range of experimental techniques tailored for these unusual assemblies will be employed. The expected outcome will be the implementation of the new design principle in multifunctional materials and structures.Read moreRead less
