The free vibration of the lattice cylindrical composite shell reinforced with Carbon Nano-tubes (CNTs) was studied in this study. The theoretical formulations are based on the First-order Shear Deformation Theory (FSDT) and then by enforcing the Galerkin method, natural frequencies are obtained. In order to estimate the material properties of the reinforced polymer with nano-tubes, the modified...

The fiber orientation state in carbon reinforced polyamide 6 composites was expressed by an order parameter (S2) that is used to express the of Nematic Liquid Crystal. S2 derived from X-ray diffraction image reflects distribution. As specimens, various content were prepared and, regardless content, and their tensile properties showed positive correlation. Furthermore, we predicted relation betw...

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).

Abstract This article analyzes the tensile modulus of shape memory polymer nanocomposites (SMPNs) at ambient temperature. Several conventional models, such as rule mixtures, Halpin–Tsai and Kerner–Nielsen, cannot practically estimate due to absence some main parameters for nanocomposites. Additionally, in Kerner–Nielsen Sato–Furukawa models are useless ineffective, small concentration high nano...

Under the influence of axial forces and uniform temperature variations, thermal buckling postbuckling composite beams reinforced functionally graded multilayer graphene platelets (GPLs) resting on nonlinear elastic foundations are examined.
