Influence of Imperfections on Axial Buckling Load of Composite Cylindrical Shells [PDF]

open access: yes, 2013
There is a strong requirement for more robust, lighter and cheaper launch vehicle structures. Unstiffened composite cylindrical shells, which are essential to the fabrication of launch vehicle airframes, are prone to buckling and are highly sensitive to ...

Simulation‐Based Analysis of Insert Pull‐Out in Nickel‐Polyurethane Hybrid Foams Using CT‐Derived Geometries

open access: yesAdvanced Engineering Materials, EarlyView.
CT‐based finite element simulations combined with in situ X‐ray computed tomography are used to analyze insert pull‐out in nickel‐coated polymer foams. Despite variations in material parameters, deformation consistently concentrates within a narrow annular region around the insert.

An imbedding method for buckling loads

open access: yesComputers & Mathematics with Applications, 1975
AbstractAn imbedding method for determining the critical length of buckling columns is presented. The method can be applied to a large class of problems and requires the integration of only one initial value equation. Integration proceeds until the integral becomes excessively large, indicating that the critical length has been reached. Alternately the

Twist buckling of veins under torsional loading [PDF]

open access: yesJournal of Biomechanics, 2017
Veins are often subjected to torsion and twisted veins can hinder and disrupt normal blood flow but their mechanical behavior under torsion is poorly understood. The objective of this study was to investigate the twist deformation and buckling behavior of veins under torsion.

Modelling Buckling and Post-buckling Behaviours of Corrugated Paperboard Structures [PDF]

open access: yes, 2012
The buckling and post-buckling behaviours of corrugated paperboard packaging structures are the focus of this study. The motivations for this study are to improve understanding of post-buckling behaviour to better predict packaging performance and ...

Numerical characterization of imperfection sensitive composite structures [PDF]

open access: yes, 2013
The need to take the imperfection sensitivity of thin-walled unstiffened cylinders into account during the early design phases motivated the development of the NASA SP-8007 guideline, which brings an empirically based lower-bound curve that gives the ...

Fabrication Routes for Ionic Conducting Fiber Strain Sensors

open access: yesAdvanced Engineering Materials, EarlyView.
Ionic conducting fiber strain sensors (ICFSs) offer compliant, textile‐integrable sensing. Thus far, the commercialization of ICFSs has been constrained by fiber fabrication routes. This review provides a fabrication‐centric analysis of ICFSs correlating processing strategies with material properties and scalability.
