In various fields of engineering, such structural elements are widely used that, from the point view their strength calculation, can be referred to thin shells (tanks, reservoirs, cylinders, etc.). When calculating thin-walled shells, a number hypotheses adopted simplify solution problem. The problem is most simply solved within framework momentless theory according which only force normal sect...

Abstract This article considers a thin-walled hollow cylinder, which is composed of fibrous and swellable hyperelastic material. The fibers are arranged in two families they taken to be parallel within each fiber family. also assumed mechanically equivalent symmetrically disposed the ground substance At instant homogeneous swelling, material incompressible. studies interplay orientation, mechan...

The integrity assessment to evaluate the safety margin of reactor pressure vessels (RPV) often considers only crack initiation and excludes propagation analysis. This contribution focuses on analysis in RPV steels. eXtended Finite Element (XFEM) method implemented ABAQUS is applied a thick-walled cylindrical specimen with circumferential at inner surface order simulate embrittled subjected Pres...

In this paper, a numerical solution has been developed for hollow circular cylinders made up of orthotropic material which is subjected to twist using micro polar theory. The effect of twisting moment and material internal length on hollow thick-walled circular cylinder made up of micro polar orthotropic material is investigated. Finite difference method has been used to exhibit the influence o...

Multi-component spin-singlet superconductors with competing 0- and $\pi$-pairing couplings, as in $s_{++}$ $s_{\pm}$ phases, are close to instabilities a spontaneous breaking of time-reversal symmetry. We demonstrate that the modification kinetic energy superconducting electrons doubly connected cylinder, determined by applied flux, generally drives transitions from chiral states configurations...

In this work, thermo – elastic analysis for functionally graded thick – walled cylinder with temperature - dependent material properties at steady condition is carried out. The length of cylinder is infinite and loading is consist of internal hydrostatic pressure and temperature gradient. All of physical and mechanical properties expect the Poisson's ratio are considered as multiplied an expone...

Coaxial nanocables of single-walled carbon nanotubes (SWNTs) sheathed with amorphous silica were synthesized by using an arc discharge method. The as-obtained nanocables were characterized by TEM, SEM and laser Raman. It was found that the nanocalbes are usually tens of microns in length and about 50 nm in diameter, and each of the cylinder-shaped nanocabels contains one to several SWNTs at the...

A thick-walled elastic cylinder contracting symmetrically is used as a model for the myocardium. The active force generated by the myocardium during systolic contraction is represented by body force (force/unit volume of myocardium). A mathematical formalism previously developed and based on large deformation analysis is used to derive a quadratic equation to represent the non-linear pressure v...
