PFA Fatigue Quasi
 

Fatigue - Quasi-Static (Low Cycle) (PFA_FATIGUE_QUASI)

View Product Datasheet (PDF)

Product Highlights:

         Effective evaluation of the fatigue life of composite and metal structures subject to static loads of constant amplitude.

         Determines the initiation site in composite and metal structures under the applied cyclic loading.

         For each stress level, the degree of cumulative damage incurred is calculated from the S-N curve, which can be derived from tests or found in the open literature.

         An efficient multi-factor interaction model (MFIM) can be used to account for a broad range of factors that affect the fatigue life of a structure such as temperature and surface finish.

         Can be used with GENOA-PA to account for the probabilistic nature of fatigue.

Applications/Benefits:

         Accurately evaluates the service life of composite or metal structures subject to static and dynamic loads of constant amplitude.

         Predicts the fatigue failure initiation site and its development in aerospace, automotive and other composite structures.

         Accounts for the probabilistic nature of fatigue.
