Figure 1

Overview of the hierarchical approach to block geometries and piecewise planar block assemblies used – (a) experimental setup showing assembled osteomorphic blocks, indenter, screw-driven frame and lateral force sensors. (b) Computational setup with the same dimensions as the experimental one (160 mm × 150 mm) and the block size of 20 mm × 20 mm × 10 mm. (c) Two-dimensional representation of shapes used for non-planar interlocking curves for block geometries, orange: square, black: osteomorphic, dark yellow: triangle. (d) As-fabricated and designed individual blocks with various geometries. (e) Representation of pyramidal surface modifications to an osteomorphic block. (f) As-fabricated and designed individual blocks, with various hierarchically interlocked surfaces. (g) Pyramidal profile design, individual pyramids approx. 1–2 mm in size.
