    Abstract

    The objective of this paper is to analyze the influence of side grooving on the ηpl factor in the ASTM Standard Test Method for JIc, a Measure of Fracture Toughness (ASTM E 813-89), for C(T) and SE(B) specimens. The method proposed by Sharobean and Landes to calculate the ηpl factor from blunt-notched specimens was utilized. Standard C(T) and SE(B) specimens were prepared out of a 30-mm-thick, 2.25 Cr-1 Mo. ASTM A-387-Gr22 type steel plate. The crack lengths considered ranged from 55% to 75% of the specimen width W, and three sets of specimens were prepared with 0% B, 25% B and 50% B double side grooving, respectively.
