Part of the TMS Symposium

When viscous fluid is injected in the gap between an elastic sheet and a rigid base plate, the sheet peels away from the base at a speed which depends on various factors. In this talk, I will describe how to model this problem mathematically using lubrication theory, and how to solve it using a matched asymptotic expansion. The method generalizes to yield over 50 different asymptotic solutions for spreading of viscous fluid under an elastic sheet.

This talk is part of the Trinity Mathematical Society series.
