Upon heating, a circular plate with immovable edge exhibits buckling, which results in ax-isymmetric postcritical bending. Progressive axisymmetric bending due to increasing thermal load the postbuckling range leads substantial redistribution of stresses and occurrence high compressive circumferential narrow zone adjacent edge. In this case, secondary buckling can occur resulting unsymmetric st...

Axisymmetric disks of eccentric orbits in near-Keplerian potentials are unstable to an out-of-plane buckling. Recently, Zderic et al. (2020) showed that idealized disk saturates a lopsided mode. Here we show this apsidal clustering also occurs primordial scattered the outer solar system which includes orbit-averaged gravitational influence giant planets. We explain dynamics using Lynden-Bell (1...

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...

One way to increase the overall stiffness of a shell structure is design shells with variable thickness. The effect thickness change on stability flexible shallow panels has been little studied due complexity solving such non-linear problems. Geometrically nonlinear deformation, buckling and postbuckling behavior thin elastic linearly subjected uniform normal pressure investigated. axisymmetric...

We analyze the formation and evolution of stellar bars in galactic disks embedded in mildly triaxial cold dark matter (CDM) halos that have density distributions ranging from large flat cores to cuspy profiles. We have applied tailored numerical simulations of analytical and live halos which include the feedback from disk/bar system onto the halo in order to test and extend earlier work by El-Z...

This paper investigates the relationship between mechanical behaviors and shape of corrugated fiberboard by means of buckling analysis, which is done by FEM (Finite Element Method). Firstly, after analyzing the structure of corrugated fiberboard a single-wall corrugated fiberboard model was built. The buckling load was measured in the ideal condition by linear buckling analysis (eigenvalue buck...

This paper studied Buckling analysis of porous truncated conical shell subjected to axial load. It is considered that a fluid undrained between porous material and the Porous material properties vary across the thickness of shell with a specific function also assumed that the edge of the shell is simply supported. The governing equations are based on the Sanders kinematics equations and the fir...

Failure in cold-formed steel beams is generally initiated by one of three instabilities: local, distortional, or lateral-torsional buckling. For cold-formed steel joists, purlins, or girts, when the compression flange is not restrained by attachment to sheathing or paneling, distortional buckling may be the predominant failure mode. Experimental results on cold-formed steel beams with unrestrai...
