Checklist

  • Delamination-prone interfaces identified (free edges, ply drops, joints)
  • Method selected: cohesive zones (initiation+propagation) or VCCT (propagation)
  • Interface strengths from test data
  • G_Ic and G_IIc from DCB and ENF tests
  • Mixed-mode criterion specified (power law or B-K)
  • Mesh adequate for process zone (cohesive) or crack front (VCCT)
  • Verification with DCB/ENF simulation completed
  • Mesh sensitivity checked
