Abstract Triply periodic minimal surfaces (TPMS) lattice structures present outstanding properties such as lightweight, high strength, energy absorption, and wave propagation control, which are extensively investigated in recent years. However, one of the main challenges when designing TPMS is proper selection cell type volume ratio order to obtain desired for specific applications. To this aim, work provides a comprehensive numerical study bandgap’s formation sub-2 kHz frequency range seven...
Poly(methyl methacrylate)-based triply periodic minimal surfaces (TPMS) structures promise great potential in phononic applications, but the complicated TPMS structure induces a design challenge for controlling their properties. Numerical acoustic simulations of seven major PMMA-based lattice are presented low-frequency sound attenuation applications while varying relative density. Except local resonances primitive and Neovius-based structures, properties other show common Bragg bandgap with...
Acoustic metamaterials with unusual properties have attracted much attention owing to their capability in controlling sound propagation. In this work, the acoustic of polymethyl methacrylate (PMMA) material based triply periodic minimal surfaces (TPMS), including Schoen's F-RD, Gyroid, and Fischer-Koch S are numerically studied. The simulation results show that these three different TPMS lattices multiple bandgaps frequency range between 200 2000 Hz. sub-700 Hz range, they commonly a bandgap...
Elastic metamaterials have attracted much attention owing to their capability in controlling elastic vibration propagation. In this work, we numerically study the properties of polymer Nylon-12 based triply periodic minimal surfaces (TPMS). Two typical lattice structures, Primitive and Schoen's F-RD surfaces, are discussed with an emphasis on relationship between filling fraction band structures. Our simulation results show that both TPMS structures exhibit bandgaps low-frequency range 1.2...
