The problem is solved three times, each time with a different element type. The element types used are VISCO106
(2-D, 4-node viscoplastic element), VISCO108 (2-D, 8-node viscoplastic element), and VISCO107 (3-D, 8-node
viscoplastic element), respectively. The plasticity is modeled using the bilinear isotropic hardening rule.

The plane strain condition is assumed along the length of the cylinder. Due to the axisymmetric loading, only a
small portion (3° span) of the cross-section is modeled each time using ten elements. Nodal rotations and displacement couplings are employed to ensure the circumferential symmetry in the deformed configuration.
To illustrate the dynamic substitution of a parameter value, an alphanumeric character parameter (element ty...
