Buckling mediated by mobile localized elastic excitations
R. S. Hutton, E. Vitral, E. Hamm +1
Experiments reveal that structural transitions in thin sheets are mediated by the passage of transient and stable mobile localized elastic excitations. These ``crumples'' or ``d-co…

A ruled narrow elastic strip model with corrected energy
E. Vitral, J. A. Hanna, L. Koens
We present a new one-dimensional model for elastic strips based on a nondevelopable ruled surface. An auxiliary field regularizes the Sadowsky narrow-strip model to allow nonzero t…

Assorted remarks on bending measures and energies for plates and shells, and their invariance properties
J. A. Hanna, E. Vitral
In this note, we address several issues, including some raised in recent works and commentary, related to bending measures and energies for plates and shells, and certain of their…
