Abstract

This paper reports the summary of J_Ic test procedures based on an ultrasonic method proposed earlier. The single-specimen J_Ic measurements for low- and intermediate-strength, high-toughness materials show excellent agreement with those determined by multispeciment test procedures. The J_Ic values of the weldment were also determined from a single specimen. In addition, a statistical analysis of the J_Ic distribution was done.
