Expert Tips

• Always consider the material’s yield strength when interpreting results.
• Effective stress is a conservative estimate; actual behavior may vary.

Interactive FAQ

What is the difference between principal and shear stress?

Principal stress acts along the axis of maximum and minimum normal strain, while shear stress acts parallel to the plane of interest.
