Results of electro-thermo-elastic analysis of a functionally graded thick-walled spherical shell made of temperature dependent materials are presented in this article. All material properties are assumed temperature-dependent and also are graded along the thickness direction based on power function. Temperature dependency is accounted for all material properties including, thermal, mechanical a...

In this paper, free and forced vibration of simply-supported Single-walled carbon nanotube is investigated under the moving nanoparticle by considering nonlocal cylindrical shell model. To validate the theoretical results, modal analysis of nanotube is conducted using ANSYS commercial software. Excellent agreement is exhibited between the results of two different methods. Furthermore, the dynam...

Current materials used for adipose tissue reconstruction have critical shortcomings such as suboptimal volume retention, donor-site morbidity, and poor biocompatibility. The aim of this study was to examine a controlled delivery system of dexamethasone to generate stable adipose tissue when mixed with disaggregated human fat in an athymic mouse model for 6 months. The hypothesis that the contin...

Aiming at the problems of complex processing technology, uneven deformation, and poor forming accuracy multi-curvature positive Gaussian slewing egg-shaped shells, it is proposed to use unidirectional loading rubber flexible medium bulging technology improve tube deformation distribution enhance plastic bionic shells. By analyzing structure manufacturing method this paper explores optimization ...

At same time, not enough attention is paid to equipment for and technologies their manufacture. The article presents a model universal filter housing cleaning liquids solid particles. Mechanical filters cartridge bag type can be used as elements. main supporting ele...

In this paper, a novel nonlocal anisotropic elastic shell model is developed to investigate the nonlinear vibrations of double-walled carbon nanotubes (DWCNTs) in framework Sanders–Koiter theory. Van der Waals interaction forces between two concentric single-walled (SWCNTs) composing DWCNT are modelled via Lennard-Jones potential and He’s formulation. linear vibration analysis, displacement fie...

This paper presents a finite element based numerical study on controlling the postbuckling behavior of thin-walled cylindrical shells under axial compression. With the increasing interest of various disciplines for harnessing elastic instabilities in materials and mechanical systems, the postbuckling behavior of thin-walled cylindrical shells may have a new role to design materials and structur...

6 LLE Review, Volume 81 Cryogenic targets for the OMEGA laser are polymer shells of ~1-mm diameter and 1to 5-μm wall thickness that require internal D2 or DT solid layers of ~100-μm thickness. Targets containing D2 may also be doped with gaseous He 3 to aid in diagnosing the implosion using the charged-particle spectrometer. To achieve the required inner ice layer, shells are first permeated to...

In this article authors obtained solutions to determine the ground curved sections free vibrations of thin-walled large-diameter pipelines with a liquid flow, based on geometrically nonlinear version semi-momentless toroidal shells medium bending theory by V.Z. Vlasov and V.V. Novozhilov. The pipeline is shell, design scheme presented in form half torus. Angle β = 1800. shell laid an elastic fo...
