Static fatigue

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 multi-axial.

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 Autodesk Nastran In-CAD software helps you evaluate this type of damage, and gain control over this response. Use the fatigue simulation tools in Autodesk Nastran In-CAD to evaluate equipment such as:

  • The fork crown on a bicycle suspension
  • Rotating shafts
  • Industrial machine equipment
  • Ship board equipment and more
