- Basic understanding of Engineering Mechanics and Strength of Materials Fundamental knowledge of Stress–Strain behavior and material properties Familiarity with Mechanical Engineering concepts (UG level is sufficient) Basic exposure to Finite Element Method (FEM) concepts (recommended but not mandatory) Ability to interpret engineering drawings and loading conditions Access to a laptop/desktop system for practice sessions (software guidance will be provided)
This session provides a practical and industry-oriented understanding of ASME Global Plastic Collapse criteria used in Design-by-Analysis (DBA) of pressure vessels and structural components. Participants will gain insight into how ASME codes ensure structural integrity against gross plastic deformation under primary loading conditions.
The session covers the fundamental concepts of plastic collapse, distinction between global and local collapse, and the role of limit load analysis as prescribed in ASME BPVC. Emphasis is placed on elastic–plastic analysis methods, interpretation of load–deformation behavior, and commonly used acceptance approaches such as the Limit Load method and Twice Elastic Slope (TES) criterion.
Real-world engineering relevance will be highlighted through simulation-based explanations, demonstrating how finite element results are used to assess collapse loads and ensure code compliance. The session also discusses material modeling requirements, common analysis pitfalls, and best practices followed in industry.
By the end of this session, participants will be able to confidently interpret ASME global plastic collapse requirements, understand when and how to apply elastic–plastic FEA, and appreciate the importance of collapse prevention in pressure vessel and structural design.
