Snap, crack and pop: The dynamics of elastic instability

If you have a question about this talk, please contact .

Elastic instabilities are ubiquitous in everyday life, from the wrinkling of skin to the rapid inversion of an umbrella. While understanding these patterns from a static point of view is relatively standard, their dynamics is more involved and relatively neglected. In this talk, I will discuss two specific examples that we have studied recently: dynamic buckling and elastic snap-through. These examples demonstrate the crucial, and perhaps surprising, role that the rate of loading plays in both how quickly instability occurs and the pattern that is ultimately observed.

This talk is part of the DAMTP BioLunch series.
