The applicability and limitations of simplified models thin elastic circular cylindrical shells for linear vibrations double-walled carbon nanotubes (DWCNTs) are considered. models, which based on the assumptions membrane moment approximate thin-shell theories, compared with extended Sanders–Koiter shell theory. Actual discrete DWCNTs modelled by means couples concentric equivalent continuous t...

Scleral thickness, especially near the optic nerve head (ONH), is a potential factor of interest in the development of glaucomatous optic neuropathy. Large differences in the dimensions of the sclera, the principal load-bearing tissue of the eye, have been observed between individuals. This study aimed to characterize the effects of these differences on ONH biomechanics. Eleven enucleated human...

An accurate nonlinear hygrothermal-electro-elastic (HTEE) buckling analysis of piezoelectric fiber-reinforced composite cylindrical shells subjected to the coupled loading effects axial compression and hydrostatic pressure was established by considering nonuniform prebuckling effect. Nonlinear governing equations were derived based on higher-order shear deformation theory Novozhilov’s shell the...

Abstract The behaviour of axisymmetric masonry shells can be simulated by a system forces constituted meridian acting in the vertical planes, and hoop circumferentially. A crucial component for assessment these structures using Modified Thrust Line Method (MTLM) is determination forces, whose computation strenuous, limiting practical application MTLM. Working around this limitation, current res...

This paper deals with introducing a unique representation of the three-dimensional Navier's equations motion in cylindrical coordinate system an exact simplified form without any approximation, aiming at facilitating solution procedure for different 3-D elasto-static and elasto-dynamic problems future. A novel elasticity including body forces is derived uncoupled terms longitudinal (axial) disp...
