Dear expert, after performing the CAESAR II pipeline analysis, how is stress assessment carried out? Is it also to perform stress assessment on primary and secondary stresses, just like in ANSYS? What are its evaluation criteria?
What does \"evaluate\" mean? As I understand it, based on the results of the stress analysis, the value should be less than 60% for the first case and less than 80% for the second case; such values fall within the acceptable range
Do you mean that the primary stress is less than 60% of the allowable stress, and the secondary stress is less than 80% of the allowable stress? I thought this software, like ANSYS, also had yield criteria similar to the Mises yield criterion and the Tresca yield criterion
No, it has nothing to do with the allowable stress; it’s just an analysis result, a percentage, and as long as this value falls within the acceptable range, that’s fine
So what percentage is appropriate? As long as it is less than 100%, that is, the stress is less than the allowable stress, is that sufficient?
CAESAR II is software developed in accordance with design specifications; the methods used for calculating stresses and assessing them are described in detail in the relevant specifications. For example, the ASME 302 design criteria – these are the most basic requirements. Then, based on these standards, various engineering companies will formulate more detailed requirements tailored to the specific projects.
