Description

This dataset accompanies the article: "Gyrobifastigium-based TPMS lattices with tuneable stiffness and energy absorption". Four TPMS topologies are investigated: Primitive (P), Hexagonal (H), Gyrobifastigium (GBF), and Elongated Gyrobifastigium (EGBF). Longitudinal and transverse loading directions are denoted by “long” and “trans”, respectively. The sheet thicknesses 0.3 mm, 0.4 mm, and 0.4 mm are labelled "t3", "t4", and "t5", respectively. For the EGBF topology “a” defines the central cuboid height and “b” defines the triangle prism height. File descriptions: "Abaqus input (.inp)": Abaqus input files for (1) the linear implicit FEA (unit cell) and (2) the nonlinear explicit FEA (cell array). "Experimental test data": Includes (1) ASTM tension/compression test data of the solid Grey V5 material. (2) Compression test data of the TPMS structures, with accompanying sample photos and video stills. "STL": Triangulated surface *.stl files of the TPMS designs. Includes (1) unit cell (shell) models for linear FEA. (2) Cell array (shell) models for nonlinear FEA (the shells are subsequently thickness offset to form solid elements in Abaqus). (3) Cell array (with thickness) volumetric models for additive manufacture. "Surface Evolver": Surface Evolver files for generating the minimal surfaces. For additional information about the project and contact details, refer to the journal paper mentioned above.
