In this paper, a nonlinear free vibration analysis of thin annular functionally graded (FG) plate integrated with two uniformly distributed actuator layers made piezoelectric (PZT4) material on the top and bottom surfaces FG is presented based Kirchhoff theory. The properties core are assumed to be in thickness direction according power law distribution terms volume fractions constituents electric potential field along simulated by sinusoidal function such that Maxwell static electricity...
Carbon nanotubes are a new class of microtubule-stabilizing agents since they interact with protein microtubules in living cells, interfering cell division and inducing apoptosis. In the present work, modified beam model is developed to investigate effect carbon on buckling microtubule bundles cell. A realistic interaction employed using recent experimental data nanotube-stabilized microtubules. Small scale surface effects taken into account applying nonlocal strain gradient theory...
Tissue engineering, whose aim is to repair or replace damaged tissues by combining the principle of biomaterials and cell transplantation, one most important interdisciplinary fields regenerative medicine. Despite remarkable progress, there are still some limitations in tissue engineering field, among which designing manufacturing suitable scaffolds. With advent additive (AM), a breakthrough happened production complex geometries. In this vein, AM has enhanced field bioprinting generating...
Breast cancer is the second most frequent cause of mortality for women and one prevalent malignant tumors that jeopardize women's health unfortunately its prevalence rising globally. has been diagnosed treated to date by employing frequently used techniques such as mammography, magnetic resonance imaging (MRI), molecular breast (MBI), biopsy, enzyme-linked immunosorbent assay (ELISA), fluorescence hybridization, polymerase chain reaction (PCR), immunohistochemistry, flow cytometry....
Negative Poisson's ratio (NPR) auxetic metamaterials are attracting significant attention because of their peculiar and interesting mechanical features. Using geometrically von-Karman nonlinear factors Mindlin plate theory, a smart multiscale hybrid (GPL/CF/PVDF) sandwich with unique two-type functionally graded graphene origami (FG-GOA) is investigated here for its vibrational behavior. The present properties the electro-elastic layers were established using Halpin–Tsai (HT) model rule...
A higher‐order non‐local strain gradient plate model developed for the vibration of piezoelectric nanofilms (PNFs) as nanoelectromechanical mass sensors is presented. The PNF carrying multiple nanoparticles at any locations subjected to thermo‐electro‐mechanical loads. Size effects are taken into consideration by introducing three different scale parameters. Using elasticity, theory and Hamilton's principle, differential equations motion derived. Closed‐form solutions obtained natural...
The present article is proposed to capture the influences of carbon nanotubes' agglomeration on natural frequency behaviors multi-scale hybrid nanocomposite plates for first time. constituent material, which a nanocomposite, consisted both macro- and nano-scale reinforcing fibers dispersed in polymer matrix. equivalent material properties are seemed be calculated coupling Eshelby-Mori-Tanaka model with rule mixture consider effects nanotubes inside probably generated clusters while finding...
