In this work, geometrically nonlinear behavior of sandwich composite beams reinforced by carbon nanotubes is studied, taking into account the influence agglomeration (CNTs). The core homogeneous while two face sheets are made CNT with effective material properties being estimated Eshelby-Mori-Tanaka approach. A first-order shear deformable beam element formulated in context total Lagrange formu...

In the present study, the magnetic field effects of the elastic response of the polymeric piezoelectric cylinder reinforced with the carbon nanotubes (CNTs) are studied. The cylinder is subjected to an internal pressure, a constant electric potential difference at the inner and outer surfaces, and the thermal and magnetic fields. The Mori-Tanaka model is used for obtaining the equivalent materi...

The aim of this paper is to investigate the effective properties Fe–TiB2 composites obtained after hot or cold rolling. elastic moduli both and rolled are measured experimentally using several methods. Microstructure analyses based on SEM observations performed characterize distribution particles cracks, then used generate 3D representative microstructures RSA method. This allows numerical dete...

the buckling analysis of annular composite plates reinforced by carbon nanotubes subjected to compressive and torsional loads are studied in this paper. the mori-tanaka method is employed to calculate the effective elastic modulus of composites having aligned oriented straight cnts. the effects of cnts volume fractions, orientation angles, boundary conditions and geometric ratio of plate are di...

In this paper, the effects of carbon nanotube (CNT) orientation and aggregation on the static behavior of functionally graded nanocomposite cylinders reinforced by CNTs are investigated based on a mesh-free method. The used nanocomposites are made of the straight CNTs that are embedded in an isotropic polymer as matrix. The straight CNTs are oriented, randomly or aligned or local aggregated int...

in this study, thermo-mechanical nonlinear vibration of a polyethylene (pe) cylindrical shell embedded in an elastic foundation was investigated. the shell is reinforced by armchair carbon nanotubes (cnts) where characteristics of the equivalent composite being determined using mori-tanaka model. the elastic medium is simulated using the spring constant of the winkler-type,  . employing nonline...

The effect of the clusterization on effective properties a composite material reinforced by MXene or graphene platelets is studied using finite element method with periodic representative volume (RVE). A hybrid 2D/3D mesh used to reduce computational complexity numerical model. Several realizations an RVE were generated increasing fractions inclusions, resulting in progressive platelets. Numeri...

The mechanical properties of nanocomposites are significantly affected by the dispersion nanofillers. In this study, synergetic effect hybrid fillers, including surfacemodified montmorillonite (MMT) nanoclay and graphene nanoplatelets (GNPs) on quality characteristics epoxy-based was investigated. It manifested that incorporation GNPs-MMT into pure epoxy improves consequently, tensile flexural ...
