These brief videos show you how to determine the durability of structures under repeated loading, including low- and high-cycle fatigue. Measure durability by the number of cycles to failure or the cumulative damage. Loading can be simple or multiaxial.
Fatigue is one of the most damaging failure mechanisms in all industries where dynamic loading is present, simply because concepts like peak load and maximum stress can’t be used for prediction. Fatigue life requires the long term damage caused by multiple loads over millions of cycles. Fatigue simulation in Inventor Nastran software offers you tools for properly evaluating this damage and gaining control over this important structural response.
