Thermal conductivity of architected cellular metamaterials

Abstract

Dedicated to my family ♥Maman nafas, Maryam joon and dawsh Pejman ii "When modern man builds large load-bearing structures, he uses dense solids: steel, concrete, glass. When nature does the same, she generally uses cellular materials: wood, bone, coral. There must be good reasons for it."

Reversible energy absorbing meta-sandwiches by FDM 4D printing

“…These structures gain the extraordinary thermo-mechanical properties from their architecture and programmed structures, rather than the bulk behavior of their elements. Meta-materials exhibit interesting features such as zero/negative Poisson's ratio (auxetic behaviors) [2], variable softening/hardening [3], effective thermal properties [4,5], and unusual dynamical behaviors [6,7].…”

Thermal performance of additively manufactured polymer lattices

“…Cellular materials are a type of porous material with a repeating cell structure and they fall within two categories: foams and lattices. In the former, a gaseous phase is randomly dispersed in a continuous solid medium, whereas the latter consists of a periodic architected cell [4].…”

Programmed Plastic Deformation in Mathematically-Designed Architected Cellular Materials

“…These architected materials were found to be revolutionary in different engineering fields. For example, as structurally efficient lightweight materials for aerospace applications [5], thermal management devices [6][7][8][9], scaffolds and body implants [10][11][12][13][14][15], wastewater treatment [16][17][18][19][20], and soft robotics [21] among others. Many architected cellular materials, varying in complexity from simple geometries such as BCC and Octet-truss [22][23][24][25] to more complex geometries such as triply periodic minimal surfaces (TPMS) [26][27][28][29][30][31][32][33][34][35][36][37], have been proposed and their topology-property relationship has been investigated both experimentally and numerically.…”
