A numerical and experimental study on buckling and post-buckling of cracked plates under axial compression load
Existence of cracks in industrial structures is one of the important causes of their failure, especially when they are subjected to important axial compressive forces that might lead to buckling. Therefore, it must be considered in stress analysis and designing and loading of such structures. In this paper, the buckling and post-buckling behaviors of stainless-steel cracked plates under axial c...
متن کاملBuckling a Semiflexible Polymer Chain under Compression
Instability and structural transitions arise in many important problems involving dynamics at molecular length scales. Buckling of an elastic rod under a compressive load offers a useful general picture of such a transition. However, the existing theoretical description of buckling is applicable in the load response of macroscopic structures, only when fluctuations can be neglected, whereas mem...

متن کاملBuckling of semiflexible filaments under compression
A model for filament buckling at finite temperatures is presented. Starting from the classical worm-like chain model under constant compression, we use a mean-field approach for filament inextensibility to find the complete partition function. We find that there is a simple interpolation formula that describes the free energy of chains or filaments as a function of end-to-end separation, which ...
متن کاملBuckling of Ge nanowires under uniaxial compression
Molecular dynamics simulations are performed to investigate the buckling properties of [100]-, [110]-, [111]-, and [112]-oriented single-crystalline germanium nanowires under uniaxial compression. The effects of simulation temperature, strain rate, and wire length on the buckling behaviour are investigated. The simulation results indicate that critical load clearly decreases with increasing tem...
