MSC.Fatigue is an advanced life simulator that allows analysts to easily transform finite element stress and strain results into fatigue life predictions. Fatigue analysis is a natural extension to a stress analysis. In fact, a fatigue analysis is basically a stress analysis that is subjected to repeated loads and that takes into account durability properties of a component or structure. MSC.Fatigue enables analysts to leverage traditional stress analyses with state-of-the-art methodologies for comprehensive durability simulations early in the design cycle. MSC.Fatigue takes stress or strain results from finite element (FE) models, subjects FE load environments to user-defined time variations, and applies cyclic material properties & damage logic to predict service life. MSC.Fatigue leverages the state-of-the-art results visualization capabilities of MSC.Patran to report damage and life predictions
