Using stability analysis of discrete elastic systems to study the buckling of nanostructures
Stubility/instability criteria of discrete elastic systems are used to study the buckling of nanostructures. The deformation of nanostructures is simulated by solving the nonlinear equations of molecular mechanics.

Nonlinear Asymmetric Buckling of Truncated Spherical Shells [PDF]
This paper is concerned with the theoretical study of buckling of truncated spherical shells. Sander’s nonlinear equations for deep shells are used and the equations of equilibrium are expressed in terms of displacements for spherical shells.

An analysis of dynamic stability of an elastic column
: By the Lyapunov direct method, dynamic stability of two conservative systems of finite degrees of freedom with one parameter is analyzed. Two Lyapunov functions are proposed for the two systems, respectively.

Localization in spherical shell buckling [PDF]
International audienceThis paper addresses localization of the deformation due to buckling that occurs immediately following the onset of bifurcation in the axisymmetric buckling of a perfect spherical elastic shell subject to external pressure.

Bifurcations of a simplified buckling problem and the effect of discretizations
The author gives a detailed description of bifurcations on the trivial solution branch \(\{\) (0,\(\lambda\)); \(\lambda\in {\mathbb{R}}\}\) of a simplified buckling problem \(\Delta u+\lambda \sin u=0\) in \(\Omega =[0,1]\times [0,1]\), \(u=0\) on \(\partial \Omega\).

Enhanced sensitivity and tunability of thermomechanical resonance near the buckling bifurcation [PDF]
The high susceptibility of ultrathin two-dimensional (2D) material resonators to force and temperature makes them ideal systems for sensing applications and exploring thermomechanical coupling.

On the analysis of viscoplastic buckling [PDF]
For elastic-viscoplastic structures the classical elastic-plastic bifurcation approach to inelastic buckling is not valid. Only an elastic bifurcation point exists in the el~tic-viscoplastic case, and the inelastic buckling behaviour is controlled by a ...

Effect of prebuckling and edge support on bifurcation buckling of torisphere, cylinder and cone [PDF]
This paper considers the buckling behaviour of commonly used shell structures in the offshore and oil industry. Three types of shells subjected to external pressure were examined, and they are: (i) torispheres, (ii) circular cylinders and (iii ...

A family of locking-free Kriging-based Timoshenko beam elements with a new implementation of the discrete shear gap technique was recently developed (referred to as K-beam-DSG1 elements). Performance of the K-beam-DSG1 elements has been shown to be very

Buckling and post-buckling of long pressurized elastic thin-walled tubes under in-plane bending [PDF]
The present paper focuses on the structural stability of long uniformly pressurized thin elastic tubular shells subjected to in-plane bending. Using a special-purpose non-linear finite element technique, bifurcation on the pre-buckling ovalization ...
