Fatigue and material failure
Load spectra, mean stress, notches, weld details and material data govern fatigue assessment. Local stress evaluation must match the selected verification method.
Modal and dynamic analysis
Natural frequencies and mode shapes identify resonance-sensitive regions. Harmonic, transient or random response can then be evaluated from the actual excitation.
Thermomechanical loads
Temperature fields are transferred to the structural model. Restrained expansion and different thermal-expansion coefficients create additional stress combined with mechanical loads.
