WebJun 17, 2024 · Goodman theory is a very useful theory that you can use for material fatigue calculation of your ductile material, that undergoes alternating stresses. Goodman equations are very basic but, definitions of variables in that theory are very important and depend on you. We have also a Von-Mises stress calculator for ductile materials. WebGoodman & Gerber The calculation method for the safety factor ( SF) is as follows: • Both stress amplitude and mean stress are varying: • Goodman: • Gerber : where ∶ Normal strain amplitude for a cycle ∶ Bi-axiality ratio ∶ Mean stress for a cycle ∶ Ultimate tensile strength (material property) ∶ Fatigue strength limit Here, i represents time step.
