Investigation of the Fracture Behavior of Scaled HY-130 Weldments

Abstract

The Naval Surface Warfare Center is developing a statistical model to predict the fracture probability of welded, ring-stiffened naval structures subjected to dynamic loads. In support of this statistical model development, SRI International is conducting a research program aimed at establishing scaling rules for fracture of weldments of different sizes and defining simple parameters to correlate the fracture damage produced in experiments with loading conditions. This report describes the approach taken to achieve these objectives and the application of this approach to undermatched (100S weld wire) welded T- joints in HY-130 steel. A similar study of Ti alloys weldments will presented in a separate report. Fracture, HY-130 Steel, Local Fracture Model, Weldments, Scaling Rules, Explosive Loading
