Progressive Composite Damage Checklist
A checklist for reviewing a progressive composite damage analysis — model setup, parameters, solver, verification and reporting.
Checklist
- Failure criterion selected and documented (Hashin, Puck, etc.)
- Damage evolution law specified — energy-based with characteristic length
- Mode-dependent degradation — fibre: E₁, matrix: E₂, G₁₂
- Fracture energies G_c obtained from test data — not invented
- Nonlinear solver with arc-length control for post-peak
- Single-element verification completed
- Mesh sensitivity checked — two densities, results similar
- Coupon verification completed
- Failure mode predicted and documented
- All material data sources documented
