A Characterization of the Fracture Resistance of Thick-Section Titanium Alloys.
Abstract
Procedures for design of structures to preclude catastropic fracture extension must be based on accurate fracture resistance characteristizations of the structural material that can only be provided by rational test procedures. For titanium alloys, the two rational fracture resistance test procedures that apply are KIc tests for brittle materials and Dynamic Tear (DT) tests for the entire range of strength and fracture resistance. The Ratio Analysis Diagram (RAD) is a framework for determining the significance of fracture resistance data in terms of stress level and crack size required for fracture. The RAD is derived from basic linear-elastic fracture concepts involving KIc and material yield strength; however, either KIc or DT test data can be indexed to the RAD. (Author)
