Composite Damage Regularisation Best Practices
Best practices for regularising composite damage models — characteristic length, energy-based evolution and mesh objectivity verification.
Best practices
- Always use fracture-energy-based evolution with characteristic length
- Understand the solver-specific characteristic length definition
- Use reasonable element aspect ratios — avoid highly distorted elements
- Verify mesh objectivity with two mesh densities — results should be similar
- If mesh-dependent: check characteristic length, evolution law, element quality
- Document the regularisation method and the objectivity verification
