Piping Inelastic Fracture Mechanics Analysis.

This report summarizes the rsults and conclusions of Task 1 and 2 of the study on ''piping inelastic fracture mechanics analysis'', Contract Number (NRC-03-79-116). In these tasks, available experimental data and the analytical methods for predicting rupture of LWR piping have been assembled and assessed. The analytical techniques investigated can be catalogued into three major groups: gross structural response analysis, semiempirical methods, and the J-controlled growth approach.
