This book was released on 1995 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents results of experimental and numerical analysis studies to investigate the relationship between J and CTOD and assess whether they are, indeed, both suitable elastic-plastic fracture characterizing parameters. Detailed elastic-plastic finite element analyses were undertaken for SE(B) specimens with a/W ratios of 0.1, 0.2, 0.3 and 0.5. Analyses were performed for a range of material stress-strain curves and yield strength levels to determine the influence of work hardening and yield strength on the J-CTOD relationship.
