| Abstract Scope |
Cellular structures are commonplace in engineering applications. Typically, cellular structures are based on patterns of periodically repeating unit cells, however the periodic nature and available symmetries of the patterns can give rise to anisotropic performance. Patterns with aperiodic order are a viable alternative that can limit anisotropy. Aperiodic patterns have rotational symmetry, yet no translational repetition and can be designed with higher orders of symmetry thereby potentially reducing the mechanical anisotropy. In this study, 2.5D honeycombs based on aperiodic tilings have been designed and manufactured using additive manufacturing. The mechanical properties and mechanical anisotropy have been characterised using a combination of modelling and mechanical testing. The outcome is a wide variation in elastic moduli, volume constant and plastic behaviour exhibited across a range of aperiodic patterns and all with relatively low levels of anisotropy |
