- Geometry
- Infinite-plate approximation with central crack half-length a=10 mm and remote tension sigma=100 MPa; use a finite plate with width >=20a.
- Material
- Constitutive or analytical definition: KI=sigma sqrt(pi a) for an infinite plate.
- Boundary conditions
- Required solver capability: xfem_or_fracture_postprocessing. Use the loading/path control stated in the setup and preserve the complete response history.
- Measured quantity
- KI=sigma sqrt(pi a)=560.49912164 MPa-sqrt(mm).
