( Home page example: Elasto-plastic buckling of heated hollow cylinder.
 
 A hollow cylinder is heated from inside, 
 and convects heat from the outer edge to the environment.
 The cylinder expands because of the heat.
 The cylinder is clamped at the bottom and top, 
 so that it buckles because of the thermal expansion.

 An updated Lagrange large deformation theory is 
 used to model the large strains and rotations in the cylinder.

 Plasticity shows up because of the high deformations.
