in this paper, the deformation of a thick-walled circular cylindrical shell of incompressible isotropic elastic material is considered. the shell, which is made of three-term strain energy function is subjected to the combined external and axial loading pressure. in order to obtain the relevant eigenvalues, which is the main objective of the work, the incremental equilibrium equations are so...

Electro-thermo-elastic stress analysis of piezoelectric polymeric thick-walled cylinder reinforced by boronnitride nanotubes (BNNTs) subjected to electro-thermo-mechanical fields is presented in this article. The electro-thermo-elastic properties of piezoelectric fiber reinforced composite (PEFRC) was studied by a modified XY micromechanical model capable of exhibiting full coupling relati...

The pneumatic control system for double-cylinder collaborative loading is extensively applied in the industry. However, compared to the hydraulic system, it is difficult for the pneumatic system for double-cylinder collaborative loading to get satisfactory effect due to strong non-linearity and low rigidity. To improve robustness of the double-cylinder collaborative loading system and increase ...

The emergence and stability of superstructured cylindrical phases in frustrated ABC linear triblock copolymers are investigated by the self-consistent field theory. Our results reveal that the complex single/double/triple helices-on-cylinder phases are formed when the straight cylinders-on-cylinder and rings-oncylinder phases are frustrated due to packing constraints. A free energy comparison i...

We numerically solve the nonlinear Poisson–Boltzmann equation for two cylinders confined by two parallel charged plates. The repulsive electrical double layer component of the cylinder pair potential is substantially reduced by confinement between like-charged plates. While the effective cylinder surface charge is increased by the confinement, the effective interaction screening length is reduc...

Aberration and retardation of the radiation within a pulsar’s magnetosphere enable a single corotating absorbing region in the outer magnetosphere to give rise to a ‘double notch’ in the pulsar’s observed radio profile. This effect requires that a pulsar has not only absorbing but also emitting regions at heights which are a significant proportion of the light cylinder radius. The known presenc...
