Applies To Product(s): AutoPIPE Version(s): 2004, XM, V8i Environment: N/A Area: Subarea: Original Author: Bentley Technical Support Group Date Logged & Current Version Jan 2015 09.06.01.10 Problem: Exactly how is AutoPIPE calculating the combined stress for a node point, equation used and individual values being applied in the equation? Answer: For Tresca stresses, AutoPIPE calculates three values for longitudinal stress as follows: SL1 = Axial (Neutral axis) SL2 = Axial + Bending (Max Long if Axial is positive) SL3 = Axial - Bending These three values are used to calculate Tresca stresses using: Similar approach is taken for Von Mises calculation.
