Dear all
What is stress intensity formula for three dimensional stress in terms of three principal stress (S1,S2,S3)?
thanks

RE: stress intensity
Your post is confusing. There are various formulas for determining stress intensity factor based on crack type and geometry. Any fracture mechanics handbook lists these formulas.
Regarding principal stresses, I would use the Von Mises equation and determine an equivalent stress to use in the desired formulas above.
