Compressive behaviour of cellular structures with aperiodic order

Cellular structures are commonplace in engineering applications, such as aerospace and medical engineering, because material-air composites offer significant mechanical benefits, for example due to improved weight-to-strength ratio. Typically, cellular based on patterns of periodically repeating unit cells, squares or hexagons, but the periodic nature available symmetries give rise anisotropic performance. This is where with aperiodic order a viable alternative. Patterns created rotational symmetry, yet no translational repetition do not possess orders symmetry from which anisotropy originates therefore have potential mitigate this issue. In study, additive manufacturing was used create 2.5D, 45% dense, honeycomb cuboids Penrose P3 tiling. These were then tested under compression loading. Honeycomb also manufactured using identical processes purpose comparison. The outcome shows improvement isotropy notably different progression strain localisation honeycombs compared comparisons during both elastic plastic deformation.
