Hello everyone,
I'm modeling a weld on COMSOL between dissimilar metals to assess the thermal stress (at low temperature so dissimilar contraction of the metals). I have some hot spots because of the geometry and wanted to used the hot spot stress method to interpolate the stress at the...
Hello again,
I apologize for the late reply.
I do consider there is thermal expansion even if it is small, I have a model to quantify how small but I'm still wondering against what values to compare the resulting stress. Maybe SMYS ? Even after going through B31.3, I wasn't able to determine...
Hello, thank you for your answer !
The standard deals with thermal stress only from a fatigue stand point and it depends on the number of cycles.
I was trying to look at the stress profile when the cold boundary temperature is first applied so I believe there is no notion of fatigue in this...
Hello all, I'm a newly graduated mechanical engineer trying to navigate all the different standards.
I have simulated the thermal stress at a circumferential weld between two different metals but I am not sure to what acceptance criteria I can compare these values. Looking into ASME B31.3, can...
