Integrated Fatigue Life Studies for Dynamic Loads
Fatigue life estimates are generally obtained with simulations conducted in time domain. This approach may not apply to many real world applications, especially when the parts being analyzed undergo complex, often random loading sequences. Dynamic nature of the loads also makes the use of time-domain analysis time consuming and cumbersome, requiring excessive analysis time and large amounts of storage space.
MSC Nastran Embedded Vibration Fatigue overcomes this problem by using the frequency domain techniques that are often used for dynamic structural analyses. This computationally efficient procedure provides life estimates orders of magnitude faster, with only a small fraction of system resources compared to traditional methods. Frequency domain methods for structural analysis also offer superior qualitative information about structural response.
