National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Comparison of Fracture Methodologies for Flaw Stability Analysis for High Level Waste Storage Tanks (U).

PB2001106026

Publication Date	2000
Personal Author	Lam, P. S.
Page Count	48
Abstract	Fracture mechanics methodologies for flaw stability analysis for Type I and II waste tanks were compared in terms of the maximum stable through-wall flaw sizes or instability lengths. The comparison was made at a full range of remote stress loading states at a specific set of mechanical properties of A285 steel and with the Type I and II tank configurations. The two general methodologies, the J-integral-tearing modulus (J-T) and the failure assessment diagram (FAD), and their specific estimation schemes were evaluated.
