Penetration Mesh Best Practices
Best practices for meshing penetration analysis — local refinement, through-thickness discretisation, mesh transitions and sensitivity assessment.
Key practices
- Use local refinement in the impact zone — 5-10 elements across projectile diameter
- Use 5-10 through-thickness elements for thick targets
- Grade mesh gradually from fine to coarse to avoid wave reflection
- Run mesh-sensitivity study with at least two densities
- Use reduced-integration elements with hourglass control
- Document mesh convergence in the analysis report
