Abstract
This paper outlines a new, simplified method for approximating K I at arrest during fast fracture events. The analysis method used in this report was developed as a simplified tool to approximate arrest conditions in a series of experiments performed by Combustion Engineering for EPRI. This simplified analysis method is applied to the CE/EPRI, HSST wide-plate, and ORNL pressurized-thermal-shock crack arrest experiments. The results presented in this paper are the first which use a single analysis technique, and thereby allow a comparison of these diverse experiments. This consistent evaluation places all the data from these experiments on an equal footing and provides a comparison with small specimen test data from the HSST program.
