Application of Two Approximate Methods for Ductile Failure Assessment

Source

Test results of large-scale specimens are analyzed on the basis of the tearing instability concept. The “Engineering Approach” of Shih et al and the extended “Failure Assessment Diagram” of Milne are used together with crack resistance J-R curves obtained from small-scale compact specimens to evaluate the loads at crack initiation and instability and the amount of stable crack growth. A detailed parameter study is conducted to show the sensitivity of the numerical results to the variation of input data such as stress-strain law, limit load, and the material resistance curve.
