- Geometry
- Paris law with C=1e-10 mm/cycle/(MPa-sqrt(mm))^2, m=2, constant DeltaK=10 MPa-sqrt(mm), a0=10 mm, N=100000 cycles.
- Material
- Constitutive or analytical definition: a(N)=a0+C DeltaK^m N for constant DeltaK.
- Boundary conditions
- Required solver capability: fatigue_crack_growth. Use the loading/path control stated in the setup and preserve the complete response history.
- Measured quantity
- da/dN=1e-8 mm/cycle and a(100000)=10.001 mm.
