The physics of frilly Swiss cheese “flowers”

For his or her experiments, the authors of the PRL paper chosen samples of Monk’s head cheese wheels from the Fromagerie de Bellelay model that had been aged between three and 6 months. They reduce every cheese wheel in half and mounted every half on a Girolle, motorizing the bottom to make sure a relentless pace of rotation and ensuring the blade was in a hard and fast place. Their measurements of how the cheese deformed throughout scraping enabled them to construct a mannequin primarily based on metallic dynamics on a two-dimensional floor that had “cheese-like properties.”

The outcomes confirmed that there was a variable friction between the core and the sting of the cheese wheel, as a result of the core stayed more energizing through the ripening course of. As a result of the tougher periphery had decrease friction with the blade, the perimeters of the cheese shavings have been uneven in thickness—therefore the resemblance to frilly rosettes.

This primarily quantities to a brand new shaping mechanism with the opportunity of having the ability to in the future program advanced shaping from “a easy scraping course of,” per the authors. “Our evaluation supplies the instruments for a greater management of flower chip morphogenesis by means of plasticity within the shaping of different delicacies, but additionally in metallic chopping,” they concluded. Granted, “flower-shaped chips have by no means been reported in metallic chopping. However even in such uniform supplies, the truth that friction properties management the metric change is especially attention-grabbing for materials shaping.”
