Impact on Thin Elastic Sheets
If you have a question about this talk, please contact Raymond E. Goldstein.
We study transverse impacts of rigid objects on a free elastic membrane, using thin circular sheets of natural rubber as experimental models. We report on a set of experiments and theoretical remarks on the occurrence of a wrinkling instability. We also describe the dynamics of the impacted membrane when it stands on a liquid substrate. Applications to the fracture pattern of glass windows and to celestial impacts will be discussed.
