Periodic cellular metals with honeycomb and corrugated topologies are widely used for the cores of light weight sandwich panel structures. Honeycombs have closed cell pores and are well suited forExpand
Misfit-energy-increasing dislocations in vapor-deposited CoFe/NiFe multilayers
Recent molecular dynamics simulations of the growth of $[{\mathrm{Ni}}_{0.8}{\mathrm{Fe}}_{0.2}/\mathrm{Au}]$ multilayers have revealed the formation of misfit-strain-reducing dislocation structuresExpand
The topological design of multifunctional cellular metals
Abstract The multifunctional performance of stochastic (foamed) cellular metals is now well documented. This article compares such materials with the projected capabilities of materials with periodicExpand
Compressive deformation and yielding mechanisms in cellular Al alloys determined using X-ray tomography and surface strain mapping
The mechanisms of compressive deformation that occur in both closed and open cell Al alloys have been established. This has been achieved by using X-ray computed tomography (CT) and surface strainExpand
Mechanical response of metallic honeycomb sandwich panel structures to high-intensity dynamic loading
Explosive tests were performed in air to study the dynamic mechanical response of square honeycomb core sandwich panels made from a super-austenitic stainless steel alloy. Tests were conducted atExpand
Mechanical metamaterials at the theoretical limit of isotropic elastic stiffness
TLDR
This work identifies a material geometry that achieves the Hashin–Shtrikman upper bounds on isotropic elastic stiffness, and finds that stiff but well distributed networks of plates are required to transfer loads efficiently between neighbouring members. Expand
The effects of topology upon fluid-flow and heat-transfer within cellular copper structures
Abstract The fluid-flow and heat-transfer features of cellular metal lattice structures made from copper by transient liquid phase (TLP) bonding and brazing of plane weave copper meshes (screens)Expand
Atomic scale structure of sputtered metal multilayers
A combined theoretical and experimental approach has been used to study nanoscale CoFe/Cu/CoFe multilayer films grown by sputter deposition. Such films have applications in sensors that utilize theExpand
Fabrication and structural performance of periodic cellular metal sandwich structures
Metallic sandwich panels with periodic, open-cell cores are important new structures, enabled by novel fabrication and topology design tools. Fabrication protocols based on the sheet forming ofExpand
Cellular metal lattices with hollow trusses
Cellular metal lattice truss structures are being investigated for use as multifunctional load supporting structures where their other functionalities include thermal management, dynamic loadExpand
