14、mber 1971.Beginning in 1972,The National Symposium on Fracture Mechanics will be sponsored by ASTM through Committee E-24 on Fracture Testing of Metals.In this volume,methods of measurement of toughness of high-toughness metals are reported.Attention is focused on a variety of tests including a new
15、fracture criteria for the elastic-plastic and fully plastic realm,the critical value of the J integral,and the relationship between the various toughness measurements.In the companion volume,STP513,the papers treat crack tip stress analysis and subcritical crack extension caused by repeated loads,en
16、vironments,and their combination.The threshold level for fatigue crack extension is given particular attention.H T.Corten Department of Theoretical and Applied Mechanics College of Engineering University of Illinois Urbana,Illinois general chairman vi Copyright by ASTM Intl(all rights reserved);Mon Dec 7 14:46:38 EST 2015Downloaded/printed byUniversity of Washington(University of Washington)pursuant to License Agreement.No further reproductions authorized.j.A.Begley 1 and J.D.Landes 1 The J Inte
