Question
The following is displayed when I run the application:
Errors:
423 LOCAL LOADS (15-R): EN 13445:2021 (2021-05), the combination of the stress ranges exceeds the maximum allowable value.
How to resolve?
Answer
To address the error in the report, please navigate to the Nozzle local load calculation section for the specific nozzle. There, you will find the following error message
The equivalent stress range value exceeds the allowable stress value. Please refer to the report snapshot below for the criteria.
Note : According to EN 13445, Clause 16.5.7.4, equation 16.5-25, the equivalent stress range should be less than or equal to 3f. However, since this value may exceed the tensile strength of the material, AutoPIPE Vessel limits the equivalent stress range value to the tensile strength of the material (Rm). Although this criterion is not explicitly mentioned in the code, it is a generally accepted practice and method.
