A Single-Specimen Determination of JIc by the Ultrasonic Method and Analysis of Its Statistical Distribution Characteristics
This paper reports the summary of JIc test procedures based on an ultrasonic method proposed earlier. The single-specimen JIc measurements for low- and intermediate-strength, high-toughness materials show excellent agreement with those determined by multispeciment test procedures. The JIc values of the weldment were also determined from a single specimen. In addition, a statistical analysis of the JIc distribution was done.
