Fatigue failure in fillet welded T joints poses critical risks for oil tankers, and understanding this is vital for marine safety.
Analysis shows joints should endure over 2.5 million cycles, surpassing Eurocode 3's conservative estimates of 0.5 million cycles.
Employing finite element analysis allowed for accurate calculation of hotspot stresses for S-N fatigue assessments.
Identifying fatigue critical zones provides a practical framework for enhancing durability and safety in marine welded structures.
