Computational Modeling – General
- Performance modeling of metallic and composite components and structures (strength, fatigue, toughness,…)
- Crack modeling – initiation, sub-critical crack growth, instability
- Leak rates, pressure loading, thrust loads, dynamic depressurization, etc.
- Weld residual stresses and corrosion effects on structural integrity
- Constitutive modeling of metals, polymeric’s and composite materials
Structural & Pipeline Integrity
