A general defioition of fracture toughness, designated by 6, is developed which is appropriate to situations of subcritical crack growth and/or kvge-scalc crack border plastic yield. The theoretical basis as well as comparisons with other proposed measures of fracture toughness are also discussed. A

Abshnct-The specimen strength ratio (R,) determined from small specimen tests was correlated with plane strain fracture toughness (RI,) values for many beats of AS33B-1 steel. A variety of toading rate and specimen size results suggest that K,, can be predicted from the small specimen strength ratio

One common concern with the manual testing of chevron notched specimens to determine fracture toughness is that it does not provide for precise control over the loading rate. This study examines the effect of loading rate on the measured fracture toughness of 20 identical hardened AISI 4140 steel sa
