How to model / perform Creep Analysis with AutoPIPE?
Creep (cold Flow) happens because of temperature, strain, and time.Different piping codes like EN 13480 may actually provide some stress categories (based on linear-elastic analysis results) for piping in creep range.
As far as modeling this analysis, at this time AutoPIPE does not deal with a full blown Creep Analysis. Creep allowable data is entered as a function of temperature in the EUROMAT library. Other codes may have creep effect taken into account in the allowable stress values. AutoPIPE material is linear elastic otherwise. No yielding or creep in the material modulus or expansion data.
