Product: ABAQUS/Standard
Young's modulus = 200 × 103 N/mm2, Poisson's ratio = 0.3, Creep law: 
= A
A
, A = 10–16, A = 10–14, 
= 5.0, and m = 0.5.
Boundary conditions:
on line AD, 
at mid-point of line AD and 
on line BC.
This is a test recommended by the National Agency for Finite Element Methods and Standards (U.K.): Test 12(b) from NAFEMS Publication Ref: R0027, “NAFEMS Fundamental Tests of Creep Behaviour,” June 1993.
The results are shown in the following table. The values enclosed in parentheses are percentage differences with respect to the reference solution.
| ABAQUS Results | |
|---|---|
| t |  |
| 0.00 | 200.00 (0.00%) |
| 1.64 | 97.44 (–0.18%) |
| 14.23 | 74.39 (–0.55%) |
| 68.75 | 60.47 (–0.79%) |
| 270.08 | 49.94 (–1.12%) |

The total creep time for this test is 1000 hours. The times listed in the above table are the times calculated by the ABAQUS automatic time stepping algorithm with CETOL = 1. × 10–5. The creep law is defined via user subroutine CREEP.
