Abstract
This report discusses an empirical correlation (developed by Battelle Columbus Laboratories in 1974) that predicts ductile failure arrest and compares it with correlations developed by other investigators. The Battelle correlation applies only to all gas decompressions and to materials that do not exhibit separations on the Charpy fracture surface. Tables are presented in this report to determine Charpy energies for ductile fracture arrest at other stress levels, for air and gas with backfilled pipe and for gas with non-backfilled pipe. The occurrence of separations on the Charpy surface provides a lower transition temperature for the material and higher toughness levels above the transition temperature.
