Rotating symetric elastic ring with a friction boundary condition

Animation of a rotating elastic ring subjected to time dependent periodical boundary conditions.

Simulation of an symetric elastic ring with a friction boundary condition on an outer radius and a periodical time dependent Dirichlet condition on the innner radius. The solutions for each discrete time step problem can be derived analytically. Theoretical backgrounds will be explained in a prepared journal paper by

J. Valdman et al.

Functional a posteriori error estimates for elasticity problems with nonlinear boundary conditions.

Type "start" to run the simulation. Note that the animation video is located as a file "ring_video.avi" in your directory.
