Scraping a soft cylindrical cheese produces thin sheets whose edges wrinkle into frilly flowers; this work identifies the mechanism as differential plastic contraction, larger in the sheet's inner region, which imposes an incompatible non-Euclidean rest metric that buckles the sheet out of plane. The differential contraction is traced to a lower friction coefficient on the cheese near its crust. Learners see how plasticity, contact friction, and thin-sheet geometry combine to control chip morphogenesis, a route generalizable to shaping food delicacies and to metal cutting.
This soft-matter-physics paper explains why scraping a cylindrical Tete de moine cheese with a rotating blade produces thin sheets whose edges wrinkle into frilly flowers. Measuring the deformation d…
