: CREEP AND PLASTICITY TEST WITH CRUSHING FOR GASKET ELEMENT [GKPE4]
*****
Notes:
1)  -- original file; tests elastic-plastic-creep via *GASKET BEHAVIOR
2) Added gasket element (#11) with gasket behavior specified via *MATERIAL
3) Added equivalent solid elem CPE4 (#21) for result comparison (with Elem-11)
