Product: Abaqus/Standard
Material:
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), n = 5, m = 0.5.
Boundary conditions:
on face ADEH, 
on face ABFE and 
on face ABCD.
Loading:
Prescribed tensile stress 
= 300 N/mm2 on face BCGF, 
= 200 N/mm2 on face CDHG, and 
= 100 N/mm2 on face EFGH.
This is a test recommended by the National Agency for Finite Element Methods and Standards (U.K.): Test 11 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.
