The Butterfly Defect Effect in Cylindrical Shell Buckling: Non-localized Interactions of Localized Imperfections
Uba K. Ubamanyu, Antoine Blond, John W. Hutchinson +1
We investigate the buckling of axially compressed cylindrical shells containing localized defects, focusing on interactions among multiple defects and between them and the shell ed…
Multiple equilibrium states of a curved-sided hexagram: Part II-Transitions between states
Lu Lu, Jize Dai, Sophie Leanza +2
Curved-sided hexagrams with multiple equilibrium states have great potential in engineering applications such as foldable architectures, deployable aerospace structures, and shape-…
Multiple equilibrium states of a curved-sided hexagram: Part I-Stability of states
Lu Lu, Jize Dai, Sophie Leanza +2
The stability of the multiple equilibrium states of a hexagram ring with six curved sides is investigated. Each of the six segments is a rod having the same length and uniform natu…
On the Elastic Stability of Folded Rings in Circular and Straight States
Sophie Leanza, Ruike Renee Zhao, John W. Hutchinson
Single-loop elastic rings can be folded into multi-loop equilibrium configurations. In this paper, the stability of several such multi-loop states which are either circular or stra…
Bending Instability of Rod-shaped Bacteria
Luyi Qiu, John W. Hutchinson, Ariel Amir
A thin-walled tube, e.g., a drinking straw, manifests an instability when bent by localizing the curvature change in a small region. This instability has been extensively studied s…
Nonlinear Dynamics of Spherical Shells Buckling under Step Pressure
Jan Sieber John W. Hutchinson, J. Michael T. Thompson
Dynamic buckling is addressed for complete elastic spherical shells subject to a rapidly applied step in external pressure. Insights from the perspective of nonlinear dynamics reve…
Probing shells against buckling: a non-destructive technique for laboratory testing
J. Michael T. Thompson, John W. Hutchinson, Jan Sieber
This paper addresses testing of compressed structures, such as shells, that exhibit catastrophic buckling and notorious imperfection sensitivity. The central concept is the probing…
