Problem statement

Geometry: Three-point-bend ENF specimen with a mid-plane starter crack; displacement control and frictionless crack faces.
Material: Constitutive or analytical definition: No target is claimed from geometry-free secondary summaries.
Boundary conditions: Required solver capability: mode_ii_delamination. Use the loading/path control stated in the setup and preserve the complete response history.
Measured quantity: Public numeric target not fixed in this corpus. Select an open ENF paper or standard geometry, record compliance and GII with provenance, then cross-check VCCT and cohesive formulations.
