Wrinkling reveals a new isometry of pressurized elastic shells
Dominic Vella, Hamid Ebrahimi, Ashkan Vaziri +1
We consider the point indentation of a pressurized, spherical elastic shell. Previously it was shown that such shells wrinkle once the indentation reaches a threshold value. Here,…
Persistence of a pinch in a pipe
L. Mahadevan, A. Vaziri, Moumita Das
The response of low-dimensional solid objects combines geometry and physics in unusual ways, exemplified in structures of great utility such as a thin-walled tube that is ubiquitou…
Curvature condensation and bifurcation in an elastic shell
Moumita Das, Ashkan Vaziri, Arshad Kudrolli +1
We study the formation and evolution of localized geometrical defects in an indented cylindrical elastic shell using a combination of experiment and numerical simulation. We find t…
