Collecting phenomena of large elastic deformation
It might be fun for us to work together to collect phenomena of large elastic deformation. These phenomena will enliven teaching and motivate research. As inspiration, here are two albums of fluid motion
In teaching large elastic deformation (notes on special cases), I describe several phenomena of large elastic deformation.
Necking or not. When pulled, a metal bar forms a neck, but a rubber band does not.
Inflation of a spherical balloon. When a balloon is inflated, the pressure-volume curve is not monotonic. Thus, when two identical balloons are connected, one balloon expands more than the other.
Inflation of a cylindrical balloon. When a cylindrical balloon is inflated, one segment of the balloon inflates first, and the remaining part of the balloon deforms slighly. As more air is pumped in, the more part of the balloon becomes inflated.
Cavitation. When a block of rubber is subject to triaxial tension, a cavity forms when the tension reaches a critical value.
Crease. When a block of rubber is compressed, the surface forms creases when the compression reaches a critical level.
In the notes on special cases, I also gave references.
