The ANSYS Fatigue Module adds the capability to simulate performance under anticipated cyclic loading conditions over a product's anticipated life span. Incorporating both Stress Life and Strain Life analyses with a variety of mean stress correction methods, including Morrow, Smith-Weston-Topper (SWT) and no mean effects, the Fatigue Module provides contour plots of fatigue life, damage, factor of safety and stress biaxiality. Additional results include rainflow matrix, damage matrix, fatigue sensitivity and hysteresis.
For Stress Life the fatigue module supports the following fatigue types:
For Strain Life the fatigue module supports the following fatigue types:
Fatigue Module contour plot of fatigue life.
Fatigue Module contour plot of fatigue factor of safety.
Fatigue Module contour plot of local stress-strain (hysteresis) response at a critical location.
