A novel quadrilateral element for analysis of functionally

This paper firstly presents numerical analyses of functionally graded porous plates/shells with graphene platelets (GPLs) reinforcement using a novel four-node quadrilateral element with five degrees of freedom per node, namely SQ4P, based on the first-order shear deformation theory and Chebyshev polynomials. The novelty of the present element is to use the high-order shape functions which

(PDF) Modeling dynamic crack propagation in fiber

It is then used to study dynamic crack propagation in unidirectional graphite/epoxy composite plates under the influence of varying impact velocities and surface friction characteristics. The dynamic J 0 integral is evaluated in each case to study the energy associated with the propagating crack tip.

IOP Conference Series: Materials Science and Engineering,

Engineered Cementitious Composites (ECC), also known as Strain Hardening Cement-based Composites, are an easily molded mortar-based composites reinforced with polymer fibers. ECCs are designed based on micromechanics and fracture mechanics theory, to feature large tensile ductility and a variety of unique properties, including tensile properties, superior to other fiber-reinforced composites.

Electrical resistivity and mechanical properties of

2019/7/1A highly conductive cementitious composite can detect subtle transformations of the associated structures by translating strain or deformation variation to electrical signals of resistivity. If conductive fibres are used for cementitious composites, there are also substantial improvements in mechanical and physical properties, such as enhanced tensile strength, ductility and durability [ 24

Interfacial Microstructure and Properties of Carbon Fiber

The performance of carbon fiber-reinforced composites is dependent to a great extent on the properties of fiber–matrix interface. To improve the interfacial properties in carbon fiber/epoxy composites, we directly introduced graphene oxide (GO) sheets dispersed in the fiber sizing onto the surface of individual carbon fibers. The applied graphite oxide, which could be exfoliated to single

Passive fire protection

Passive fire protection (PFP)[1] is an integral component of the components of structural fire protection and fire safety in a building. PFP attempts to contain fires or slow the spread, such as by fire-resistant walls, floors, and doors. PFP systems must comply with the associated listing and approval use and compliance in order to provide

the dynamic characteristics of laminated plates reinforced with graphite mesh [7]. In this study, an analytical dynamic finite element model was developed to evaluate the natural frequencies and mode shapes for structures subjected to different boundary

Mechanical and damping properties of CNT

The mechanical and damping properties of CNT-reinforced cementitious composite structures were experimentally examined. In the experiments, an aromatic modified polyethylene glycol ether named TNWDIS and polyvinylpyrrolidone (PVP) were used to disperse CNTs, which were ultra-effective and compatible with cement hydrates.

Rose et al. [15] investigated Lamb wave propagation in unidirectional, two-directional, and quasi-isotropic graphite-epoxy composite panels. They derived polar characteristics of phase and group velocities of the low-frequency S0 Lamb mode.

Enhancement of ultrahigh performance concrete material

2014/1/11. Introduction Ultrahigh performance concrete (UHPC) is an emerging class of cementitious composites with outstanding material properties [1-4]. UHPC offers very high strength (compressive strength 150 MPa, tensile strength 8MPa) [2, 5, 6], toughness [3], and

Exfoliated Graphite Nanoplatelet

In this study, we investigated the gauge factor and compressive modulus of hybrid nanocomposites of exfoliated graphite nanoplatelets (xGnP) and multiwalled carbon nanotubes (MWCNTs) in a polydimethylsiloxane matrix under compressive strain. Mechanical and electrical tests were conducted to investigate the effects of nanofiller wt %, the xGnP size, and xGnP:MWCNT ratio on the compressive

Materials

Despite several studies using natural graphite as a conductive additive, the effect of its fineness on the cementitious composite's performance has not been explored. This study experimentally investigated the effect of three graphite products of varying fineness on the early age, mechanical, and electrical conductivity performance of cement pastes.
