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…
