Fatigue - Harmonic Fatigue (High Cycle) (PFA_FATIGUE_HARMONIC)

View Product Datasheet (PDF)

Product Highlights:

·         Evaluates the fatigue life of composite and metal structures subject to dynamic loads of constant amplitude.

·         Determines the fatigue failure 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.

·         The degradation S-N curve for a considered material.

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 structural components.

·         Accounts for the probabilistic nature of fatigue.
