Post-buckling behavior of stiffened cylindrical shell and experimental validation under non-uniform external pressure and axial compression

, 2021
External pressure and axial compression are common load cases for stiffened cylindrical shells in underwater structures. Once these two load cases are combined, the buckling behavior will become quite complex, especially when the external pressure is non-

Assessment of web post buckling resistance in steel-concrete composite cellular beams

, 2021
This paper aims to investigate the ultimate strength of steel-concrete composite cellular beams, considering the web post buckling. The numerical model is calibrated via experimental tests consolidated in the literature by geometrical non-linear analyses.

Three-dimensional parametric resonance of fluid-conveying pipes in the pre-buckling and post-buckling states

, 2021
The paper presents a model of describing three-dimension parametric vibrations of a simply supported pipe conveying pulsating fluid. The three-dimensional motion equation of the system is a set of two nonlinear partial differential equations developed on

Post-buckling analysis of magneto-electro-elastic composite cylindrical shells subjected to multi-field coupled loadings

, 2021
Axial compressed cylindrical shell has a post-buckling equilibrium state far below the critical load of eigenvalue buckling, therefore the post-buckling analysis could provide a more reliable instability criterion for engineering design.

On instabilities and post-buckling of piezomagnetic and flexomagnetic nanostructures

, 2020
We focus on the mechanical strength of piezomagnetic beam-like nanosize sensors during post-buckling. An effective flexomagnetic property is also taken into account. The modelled sensor is selected to be a Euler-Bernoulli type beam.

Post buckling of micromachined beams

Journal of Micromechanics and Microengineering, 1994
The static deformation of micromachined beams under prescribed in-plane compressive stress is studied by analytical and experimental means over the pre-buckling, transition, and post-buckling load ranges. The finite amplitude of the beam in its post-buckled state is predicted by modeling the non-linear dependence of its compressive stress on the out-of-

An element-free study of variable stiffness composite plates with cutouts for enhanced buckling and post-buckling performance

, 2020
In this paper, an efficient element-free modeling framework for variable stiffness composite laminates with cutouts is developed. In comparison with other numerical methods or semi-analytical methods, element-free meshless methods offer many advantages ...
