- Geometry
- Plane-stress benchmark: E=200000 MPa, nu=0.3, eps_c=A sigma^n t^m, A=3.125e-14 per hour, n=5, m=0.5; prescribed ux=0.1 and uy=-0.1.
- Material
- Constitutive or analytical definition: Published NAFEMS R0027 result reproduced in an open vendor benchmark.
- Boundary conditions
- Required solver capability: primary_creep_plane_stress. Use the loading/path control stated in the setup and preserve the complete response history.
- Measured quantity
- Open Abaqus table checkpoints: strain-hardening sigma_xx=61.08 MPa at 0.52 h, 45.89 MPa at 8.39 h, and 27.34 MPa at 1000 h.
