Using stability analysis of discrete elastic systems to study the buckling of nanostructures

Archives of Mechanics, 2012
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.

Bifurcations of a simplified buckling problem and the effect of discretizations

manuscripta mathematica, 1991
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 \(\partial \Omega\).

Free-Vibration and Buckling Analyses of Beams using Kriging-Based Timoshenko Beam Elements with the Discrete Shear Gap Technique

Civil Engineering Dimension
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
