Critical Review of Fracture and Fatigue Analysis.

reportActive / Technical Report | Accession Number: AD0742753 | Need Help?

Abstract:

The state of knowledge in fracture and fatigue analysis is reviewed in order to provide a technical background for the development of fatigue design procedures for submarine hulls. Special emphasis is placed on analytical fracture mechanics approach. Results are presented for the stress and strain distribution near the crack tip. Current fracture criteria and subcritical crack initiation and propagation laws are summarized including the environmental effects. Author
