ProductsAbaqus/Standard Elements testedC3D20R Problem descriptionMaterial: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. Boundary conditions:on face ADEH, on face ABFE, on face ABCD, on face BCGF, on face CDHG, and on face EFGH. Reference solutionThis is a test recommended by the National Agency for Finite Element Methods and Standards (U.K.): Test 6(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. Results and discussionThe results are shown in the following table. The values enclosed in parentheses are percentage differences with respect to the reference solution.
RemarksThe 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. × 10−4. Input files
