Stress-life analysis in Specialist Durability

1. Determine the local load histories:By superposing the calibrated load histories according to the entries in the Load-FE Assignment.From Finite Element Analysis runs.

2. Calculate local load cycles.

3. Get the SN-curve from the Specialist Durability materials.

4. Check for endurance limit and endurance limit correction.

5. Check for mean stress correction for each bin.

6. Check for damage accumulation for the loops and the residue separately.

7. Check for damage accumulation for the cycles and residue.
