LINEAR STATIC ANALYSIS

• Strength and fatigue checks - AISC, ASME, API, DNV rules
• Welding checks - DNV, API, AWS rules

---

CONTACT ANALYSIS

• Linear contacts (Glue/Bonded) and non-linear (friction)
• Preloaded bolts

---

ELASTO-PLASTIC AND LIMIT STATE ANALYSIS

• Elastic models of materials
  • ASME method
