Problem:

Exactly how is AutoPIPE calculating the combined stress for a node point, equation used and individual values being applied in the equation?

Solution:

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.
