Abaqus General Skills for FFS ,Structure Integrity and Assessment based on API, BS, ASME and DNV:    • Abaqus General Skills for FFS ,Structure I...  
Including 26 hours of step-by-step tutorials.

Don’t hesitate to ask any questions you might have about the explanations presented in this video using the comments below. We try to answer all questions regarding the video details in the comments below.

In the design-by-analysis of pressurized equipment, Plastic Collapse failure must be checked in accordance with ASME Section 8, Division 2, Part 5. Also, when the pressurized equipment includes internal or external corrosion, Plastic Collapse must be rechecked. This tutorial explains how to model general and local metal loss (Parts 4 and 5 of API 579) and check the Plastic Collapse failure. The procedure for assessment of Plastic Collapse is similar between API 579 and ASME Section 8. The explanations of both standards will be addressed in the tutorial and applied to both intact and corroded pipes. The procedure of simulating Plastic Collapse is the same for pressurized equipment, whether the structure is intact or not. As the pipe is thin, it will be modeled using shell elements.

For the thin equipment, both solid and shell modeling can be used. In shell modeling, there is no need to define elements through the thickness, so the simulation will be much more efficient without sacrificing accuracy. The instructions for the standards are the same for shell and solid modeling.
