Fundamentals of Design by analysis approach of ASME Boiler and Pressure vessel code Sec VIII Division 2.

The topics that will be covered in this course will be –

1. Failure Mechanisms addressed in ASME SEC VIII D2- Gross plastic deformation, Ratchetting and Fatigue, Instability.

2. The difference between design by analysis and design by rule- Discussion of the concepts.

3. Gross plastic deformation as a failure mode- Real life examples, the concept of limit state analysis.

4. Incremental plasticity as a failure mode- Real life examples elucidating the concept of Ratchetting.

5. Alternate plasticity or low cycle fatigue as a failure mode- Discussion of the failure mechanism of fatigue.

6. Various approaches to Fatigue analysis- Stress, Strain and Fracture mechanics-based approach.

7. Polished bar versus structural stress approach- Fundamental issues and theoretical background.

8. Limit and Elastic plastic analysis- Theoretical background with some real-life examples.

9. Computer implementation of design by analysis approach- A brief overview of WRC 429.
