The indentation of standard viscoelastic solids, that is, the three-element material, by an axisymmetric, flat-ended indenter has been investigated theoretically. Under boundary conditions flat-punch a half-space, solutions equations deformation are derived for material. Their generality resides in their inclusion compressible as well incompressible solids. They cover two transient situations: creep test and load-relaxation test. In experimental tests applicability, nanoindentation...
Lightweight origami structure has received increasing attention in the past years. This paper presents a new origami-inspired honeycomb sandwich plate, taking inspiration from two emerging structures reported literatures. The purpose of this work was to investigate influence structural parameters on impact response and demonstrate outperformance novel structure. low-velocity investigated experimentally numerically. And numerical prediction closely matched experimental results terms...
In this study, the impact response, damage accumulation, interlaminar and intralaminar energy dissipation distributions of patch-repaired carbon fiber reinforced polymer (CFRP) laminates under repeated impacts were studied by combining experimental numerical methods. A three-dimensional finite element model (FEM) based on continuum mechanics (CDM) cohesive zone (CZM) was performed using ABAQUS/Explicit to simulate experiments (at 10 J ~ 20 J). The influence (5 15 J) explored calculations. It...
The mechanical behavior of plain woven Carbon Fiber-Reinforced Polymer (CFRP) composites under Three-Point Bending (TPB) is investigated via experimental and numerical approaches. Multiscale models, including microscale, mesoscale macroscale have been developed to characterize the TPB strength damages. Thereinto, Representative Volume Elements (RVEs) microscale structures are established determine effective properties carbon-fiber yarn CFRP composites, respectively. Aimed at accurately...
With the wide application of hydrogen-doped natural gas (HBNG) in end users, laying pipelines urban, comprehensive pipe corridors has become increasingly common. However, leakage and diffusion confined or semi-confined spaces (e.g., utility corridors) can pose a severe safety hazard, as methane hydrogen mixtures have higher risk explosion. Therefore, studying gas's behavior gallery is essential to ensure its safe operation. This paper establishes numerical model study law leakage,...
To investigate the mechanical behavior of single-lap joints (SLJs) adhesively bonded structure carbon fiber reinforced polymer (CFRP) laminates under low-velocity impact (LVI) and tensile-after (TAI), tests simulations were carried out. A finite element model (FEM) was established based on cohesive zone (CZM) Hashin criterion to predict damage evolution process adhesive film, intra- inter-laminar SLJs CFRP laminates, its effectiveness verified by experiments. Moreover, three different...
Instrumented nanoindentation tests were used to investigate the mechanical properties of Zr52.5Cu17.9Ni14.6Al10Ti5 bulk metallic glass. The corresponding loading strain rates ranged from 0.002 s−1, 0.02 s−1 0.2 s−1. Plastic flow this material exhibited remarkable serrations at low and increasingly became weakening until disappearance with increasing indentation rate, implying strong rate sensitivity. A significant pile-up around indents was observed through atomic force microscopy, which...
Lightweight sandwich structures have been receiving significant attention. By studying and imitating the structure of biomaterials, its application in design has also found to be feasible. With inspiration from arrangement fish scales, a 3D re-entrant honeycomb was designed. In addition, stacking method is proposed. The resultant novel utilized as core order increase impact resistance under loads. created using printing. low-velocity experiments, mechanical properties with...
A floating breakwater can significantly reduce the wave invasion of marine structures and provide a safe construction environment service for attenuation protection structures. With development utilization resources, application breakwaters in engineering is becoming more important; research on integrated systems wave-energy converter (WEC) also valuable. However, existing has not yet systematically improved influencing factors performance summary mechanism; there are few summaries about...
Abstract Patch‐repaired plain woven composite structures were exposed to internal damage caused by impact during service, which reduced mechanical properties. A multi‐scale modeling strategy was proposed study the resistance characteristics of patch‐repaired carbon‐fiber‐reinforced‐polymer (CFRP) laminates. The micro representative volume element (RVE) extracted from yarn; a local homogenization method used obtain equivalent cross‐ply laminate (ECPL) cells corresponding mesoscale RVE. finite...
A liquid nitrogen cooling system was developed to ensure the successful ultrasonic testing of composite materials characterize very High Cycle Fatigue (VHCF) carbon fiber reinforced plastics (CFRP).
