Smith Diagram Stress. The smith diagram only applies for a defined number of load reversals. Wst1 draws smith diagrams and haigh diagrams for tension pressure bending and torsion.
The smith diagram only applies for a defined number of load reversals. The higher the notch effects and internal stresses of a component the more the smith diagram resembles two parallel lines i e the stress difference δδ 2 δ a is almost constant. In geomechanics usage the normal stresses are positive when compressive.

This characterizes the area of the so called low cycle fatigue. In geomechanics usage the normal stresses are positive when compressive. Using an auxiliary line under 45 degrees the stress amplitude can also be determined relative easily as the distance to the goodman line. This means it is a cross section through the wöhler curve.
