Periodic honeycombs have been used for their high strength, low weight and multifunctionality. The quasi-static dynamic compressive responses of three types additively manufactured AlSi10Mg honeycomb structures, specifically a single-scale two hierarchical with levels hierarchy, respectively, investigated using experimental measurement finite element (FE) simulations. validated FE simulation has employed to investigate the effects relative density key parameters. following failure modes...
Tailoring light-matter interactions via plasmonic nanoantennas (PNAs) has emerged as a breakthrough technology for spectroscopic applications. The detuning between molecular vibrations and resonances, fundamental inevitable optical phenomenon in interactions, reduces the interaction efficiency, resulting weak molecule sensing signal at strong state. Here, it is demonstrated that low efficiency from can be tackled by overcoupled PNAs (OC-PNAs) with high ratio of radiative to intrinsic loss...
Sandwich beams comprising identical face sheets and a square honeycomb core were manufactured from carbon fiber composite sheets. Analytical expressions derived for four competing collapse mechanisms of simply supported clamped sandwich in three-point bending: shear, microbuckling, wrinkling, indentation. Selected geometries tested to illustrate these modes, with good agreement between analytic predictions measurements the failure load. Finite element (FE) simulations bending responses also...
An experimental and numerical investigation was undertaken to characterise the collapse of 3D orthogonal woven carbon fibre composites during load cases in-plane tension, compression out-of-plane bending. Two different architectures, varying only by density through-thickness reinforcement, were investigated. Cantilever beam tests carried out isolate two distinct mechanisms, i.e. bending governed shear deformation. A qualitative comparison made with a similar UD-laminate material. exhibited...
The carbody shaking phenomenon (CSP) can greatly reduce the ride comfort of high-speed trains. To investigate abnormal vibration feature and causes CSP, extensive field measurements numerical simulations were conducted. A three-dimensional rigid-flexible coupled dynamic model a vehicle is constructed to reproduce CSP reveal key influence factors, in which finite element updated based on experimental modal data. test show that main frequency accelerations appear around 7.90 Hz, close natural...
Natural cellular materials, such as marine mussels, honeycombs, woods, trabecular bones, plant parenchyma, sponges and protoreaster nodosus, may benefit from the disorderliness within their internal microstructures to achieve damage tolerant behaviors. Inspired by this, we have created quasi-disordered truss metamaterials (QTMs) via introducing spatial coordinate perturbations or strut thickness variations perfect, periodic lattices. Numerical studies suggested that QTMs can exhibit either...
3D orthogonal woven composites are receiving increasing attention with the ever-growing market of composites. A current challenge for these materials' development is how to improve their damage tolerance in and layer-to-layer structures under extreme loads. In this paper, a reduction strategy proposed by combining structural electromagnetic properties. An integrated experimental platform designed power system, drop-testing machine, data acquisition devices investigate effects pulse impact...
Recent developments in electric vehicles have heightened the need for high-efficiency heat pump technology to improve cruising range and cabinet thermal comfort. As key component a system, compressor has significant impact on system performance. In this work, numerical model of consisting variable displacement (VDC) model, speed (VSC) exchanger is presented compare two major types compressor. The simulation executed across diverse array conditions assess performance disparity between...
Abstract Aerogels excel in thermal insulation due to their porous structure, but limited mechanical strength restricts broader applications. Thus, the development of aerogel composites for equipment/personnel against and hazards extreme environments necessitates more design paradigm. Herein, a novel double‐crosslinked polyimide composite (PIAC) with an organic–inorganic hybridization approach is prepared. This composite, incorporating amino‐modified SiO 2 nanoparticles reduce...
La<sub>0.8</sub>Sr<sub>0.2</sub>Ga<sub>0.8</sub>Mg<sub>0.2</sub>O<sub>3</sub> (LSGM) is considered a promising electrolyte material for intermediate-temperature solid oxide fuel cells (IT-SOFCs) because of its high ionic conductivity.
Clamped rectangular orthogonal 3D woven carbon composite beams under ballistic impact at a velocity range 60ms-1⩽v0⩽190ms-1 were investigated in order to understand the damage mechanisms within material and role of through-the-thickness (TTT) reinforcement. Experimental tests revealed three distinct categories beam response: (i) low impacts (v0<110ms-1) which featured projectile rebound, with dominant matrix cracking localised fibre fracture, (ii) medium (110ms-1⩽v0<148ms-1) exhibited...
