Problem statement

Geometry: Use the center-crack case with E=210000 MPa and nu=0.3 under plane strain.
Material: Constitutive or analytical definition: G=KI^2/E' with E'=E/(1-nu^2) in plane strain.
Boundary conditions: Required solver capability: energy_release_rate. Use the loading/path control stated in the setup and preserve the complete response history.
Measured quantity: E'=230769.230769 MPa and G=KI^2/E'=1.36135681656 N/mm.
