About the course

The ASME Boiler & Pressure Vessel section VIII code is the most frequently used pressure vessel design code in the world. Two design approaches are present in the code: design by rules and design by analysis. Design by Analysis in ASME VIII-2 Part 5 is used to complement the Design by Rules parts of the code. Why might this be necessary? Perhaps a feature is located too close to a discontinuity or has a non-standard configuration, perhaps a detailed fatigue calculation is required or loadings other than pressure are present?

This course covers how to conduct Design by Analysis code compliance checks for rupture, ratcheting, fatigue and buckling load cases.

During which topics such as the difference between primary or secondary stresses, the influence of weld type on fatigue life and obtaining the structural stress will be addressed using FEM software.

The course consists of 5 online, self-study courses combined with 2 online live sessions with the instructor. All training content is provided through your EngineeringTrainer account.

After the course you maintain 1-year unlimited access to the course. This allows you to perform courses again when you need to refresh the knowledge for your projects.
