Buckling Knockdown Factors of Composite Cylinders under Both Compression and Internal Pressure

open access: yesAerospace, 2021
The internal pressure of a thin-walled cylindrical structure under axial compression may improve the buckling stability by relieving loads and reducing initial imperfections. In this study, the effect of internal pressure on the buckling knockdown factor

Semi-classical buckling of stiff polymers

open access: yes, 2007
A quantitative theory of the buckling of a worm like chain based on a semi-classical approximation of the partition function is presented. The contribution of thermal fluctuations to the force-extension relation that allows to go beyond the classical ...

Finite bending and pattern evolution of the associated instability for a dielectric elastomer slab [PDF]

open access: yes, 2018
We investigate the finite bending and the associated bending instability of an incompressible dielectric slab subject to a combination of applied voltage and axial compression, using nonlinear electro-elasticity theory and its incremental version.

A Nonlinear Thin-Wall Model for Vein Buckling [PDF]

open access: yesCardiovascular Engineering and Technology, 2010
Tortuous or twisted veins are often seen in the retina, cerebrum, and legs (varicose veins) of one-third of the aged population, but the underlying mechanisms are poorly understood. While the collapse of veins under external pressure has been well documented, the bent buckling of long vein segments has not been studied.

Analysis of Buckling Propagation of the Composite Structure of Sandwich Pipe at External Pressure

open access: yesShiyou jixie, 2020
The huge hydrostatic pressure in the deep sea always causes local buckling instability on the pipeline. In this paper, ABAQUS, a nonlinear finite element software, is used to establish a 3D numerical, nonlinear, quasi-static buckling propagation model ...

Multi-step self-guided pathways for shape-changing metamaterials [PDF]

open access: yes, 2018
Multi-step pathways, constituted of a sequence of reconfigurations, are central to a wide variety of natural and man-made systems. Such pathways autonomously execute in self-guided processes such as protein folding and self-assembly, but require external

The Instability Improvement of the Symmetric Angle-Ply and Cross-Ply Composite Plates with Shape Memory Alloy Using Finite Element Method

open access: yesAdvances in Mechanical Engineering, 2014
Shape memory alloy (SMA) wires were embedded within laminated composite plates to take advantage of the shape memory effect property of the SMA in improving post-buckling behavior of composite plates.

Multimodal Mechanical Testing of Additively Manufactured Ti6Al4V Lattice Structures: Compression, Bending, and Fatigue

open access: yesAdvanced Engineering Materials, EarlyView.
In this experimental study, the mechanical properties of additively manufactured Ti‐6Al‐4V lattice structures of different geometries are characterized using compression, four point bending and fatigue testing. While TPMS designs show superior fatigue resistance, SplitP and Honeycomb lattice structures combine high stiffness and strength. The resulting
