Abstract Truss structures with obvious periodical repetition in civil engineering are commonly used long-span bridges and large-span buildings. Based on phononic crystal theory, have the potential to develop elastic wave bandgaps, which conduct noise attenuation or novel nondestructive testing. However, there needs be more current knowledge about truss bandgaps their applications. This study investigates transmission characteristics of two typical analytically numerically. We first decoupled unit cells from large structures. Then, we proposed a standard analytical model get dispersion relationship The is verified by finite element method. results show that structure A could generate bandgap 1032 2065 Hz, while B 982 1980 Hz. mode analysis further reveals mechanism Bragg scattering rather than local resonator. through frequency domain analysis, agrees well bandgaps. To exhibit how conducts applications testing, employ case studies illustrate propagation waves testing for attenuate waves. Defects abnormal transmission, applied

Mechanical and shape-memory properties of TPMS with hybrid configurations and materials

International Journal of Smart and Nano Materials, Год журнала: 2024, Номер 15(4), С. 786 - 810

Опубликована: Окт. 1, 2024

Triply periodic minimal surface (TPMS) structures with excellent properties of stable energy absorption, light weight, and high specific strength could potentially spark immense interest for novel programmable functions by combining smart materials, e.g. shape memory polymers (SMPs). This work proposes TPMS lattices hybrid configurations materials that are composed viscoelastic shape-memory the aim to bring temperature-dependent mechanical additional dissipation mechanisms. Different diverse polylactic acid (PLA), fiber-reinforced PLA, polydimethylsiloxane (PDMS) induced, generating five types lattices, including (Schoen's I-WP) IWP uniform lattice, lattice density gradient, configurations, filled PDMS, which fabricated 3D printing. The fracture morphologies distribution carbon fibers demonstrated via scanning electron microscopy a focus on influence fiber properties. Shape recovery tests conducted, proves good reusable capability lattice. combined methods experiments numerical simulation adopted evaluate properties, presents multi-stage absorption ability tunable vibration isolation performances associated temperature hybridization designs. can promote extensive research provide substantial opportunities in development functional applications.
