Functionally graded and multi-morphology sheet TPMS lattices: Design, manufacturing, and mechanical properties.
TL;DR: Relative density grading, cell size grading, and multi-morphology (lattice type grading) are mechanically investigated for sheet-based lattices with topologies based on triply periodic minimal surfaces, and FE analysis revealed that sheet-networks multi- morphology lattices exhibit higher elastic properties as compared to solid-network multi- Morphology lattice.

TL;DR: In this article, the authors studied the compression-compression fatigue behavior and the underlying fatigue mechanism of Gyroid cellular structures (GCS), a typical TPMS porous structure, and found that the fatigue ratio of GCS reaches 0.35 for as-built samples and can be raised to 0.45 after sandblasting treatment.

Mechanical and energy absorption characteristics of additively manufactured functionally graded sheet lattice structures with minimal surfaces
TL;DR: In this paper, the performance of uniform sheet (US) and functionally graded sheet (FG) lattice structures with primitive (P) and gyroid (G) minimal surfaces were fabricated by selective laser melting (SLM) using Ti-6Al-4V powder.

TL;DR: The linear elasticity of anisotropic cellular solids is studied in this article. But the authors focus on the design of sandwich panels with foam cores and do not consider the properties of the materials.

Fracture characteristics of three metals subjected to various strains, strain rates, temperatures and pressures
TL;DR: In this paper, a cumulative-damage fracture model is introduced which expresses the strain to fracture as a function of the strain rate, temperature and pressure, and the model is evaluated by comparing computed results with cylinder impact tests and biaxial (torsion-tension) tests.

Manufacture, characterisation and application of cellular metals and metal foams
TL;DR: The possibilities for manufacturing metal foams or other porous metallic structures are reviewed in this article, where various manufacturing processes are classified according to the state of matter in which the metal is processed, such as solid, liquid, gaseous or ionised.

Dislocation-mechanics-based constitutive relations for material dynamics calculations
TL;DR: An improved description of copper and ironcylinder impact (Taylor) test results has been obtained through the use of dislocation-mechanics-based constitutive relations in the Lagrangian material dynamics computer program EPIC•2.
