- Geometry
- Uniaxial constant stress 100 MPa, Norton A=1e-10 MPa^-3 s^-1 and n=3 for 100 s.
- Material
- Constitutive or analytical definition: dot(eps_c)=A sigma^n.
- Boundary conditions
- Required solver capability: norton_creep. Use the loading/path control stated in the setup and preserve the complete response history.
- Measured quantity
- creep rate=0.0001 1/s and creep strain at 100 s=0.01.
