Fig. 3: Structure and material testing of the metatarsal pad.
From: Computationally tuned dual-layer lattice pads adapted to gait-induced pressure distribution
A Schematic illustration of the working principle of the metatarsal pad and a cross-sectional view of its internal structure. B Structural parameters and corresponding structural types. When the relative sizes of parameters A and B vary, the internal structure exhibits different configurations. The right panel shows a 2D cross-sectional view under specific parameter settings. C Tensile test samples and recorded data for material property evaluation, along with FE analysis of compression tests on cylindrical samples.
