FATIGUE CRACK PROPAGATION IN A514 BASE PLATE AND WELDED JOINTS

The objectives of the report are two-fold. The first part deals with the fatigue response of the base plate material; the effect of mean load variations, specimen configuration and thickness on fatigue crack propagation (FCP) is examined. Having established the propagation characteristics of the base metal, FCP in weld metal and heat affected zone (HAZ) was evaluated with respect to suitable variables in the second part of the investigation.
