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…

Energies for elastic plates and shells from quadratic-stretch elasticity
E. Vitral, J. A. Hanna
We derive stretching and bending energies for isotropic elastic plates and shells. Through the dimensional reduction of a bulk elastic energy quadratic in Biot strains, we obtain 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…
