PROCEDURE

• Extract stress histories and calculate fatigue
  lifes from stress data from multiple FEA
  solutions
• User selects the FEA solution sets used to define
  each load condition

• Determine plane of critical fatigue damage
• Calculate stresses and fatigue damage in angular
  increments about each node
• Sum damage for each angular increment

• Display Results

Wheel Fatigue Job Control Results
After selecting full analysis on the job
control form, the software produces a stress-time
history for each node containing N points
(extracted from the N load cases). It then
conducts a rainflow cycle count and calculates
fatigue damage (a typical SN analysis).
