Product: ABAQUS/Standard
Young's modulus = 200 × 103 N/mm2, Poisson's ratio = 0.3, Creep law: 
= A
, A = 3.125 × 10–14 per hour (
in N/mm2), 
= 5.
Boundary conditions:
on line AD, 
on line AB, 
on line BC and 
on line CD.
This is a test recommended by the National Agency for Finite Element Methods and Standards (U.K.): Test 5(b) from NAFEMS Publication Ref: R0027, “NAFEMS Fundamental Tests of Creep Behaviour,” June 1993.
The time marching program provided in Appendix B of the NAFEMS Publication can be used to obtain the stress variation with time.
The results are shown in the following table. The values enclosed in parentheses are percentage differences with respect to the reference solution.
