Effect of High Strength Steels on Strength Considerations of Design andConstruction Details of Ships

摘要

Fatigue cracking continues to be a major cause of extensive and costly shiprepair work. In the past 10 years, the use of high strength steel (HSS) has come under scrutiny as a significant contributor to fatigue cracking. The investigation calls attention to the problem areas of high strength steel details. Also, a general methodology for assessing the fatigue strength of structural details is presented using existing technology. Examples using this methodology are presented for existing problematic high strength steel details.
