RSE-M/RCC-MRx Analytical scheme for the J parameter calculation on cracked pipes and vessels submitted to through thickness thermal loading
Year: 2015
Type: conference-paper
Abstract: This article deals with the analytical scheme to estimate J for pipes and vessels submitted to through thickness thermal loading, combined or not with mechanical loading, and codified within the RSE-M/RCC-MRx appendixes devoted to Fracture Mechanics Assessment.This scheme basically relies on an elastic J calculation and on a specific plastic correction (named k th ) which allows taking into account the stress relaxation observed for such loading situations.The work specifically dedicated to thermal loading development was performed in parallel by two teams, resulting in two options available for the k th correction coefficient.The purpose of this paper is to present the background of these two options, completed by the associated validation through a comparison with reference F.E. solutions.Additionally, recent developments performed for weld joints (evaluation of the effect an overmatch weld joint) and for residual stresses consideration are presented.Those developments are resulting from on-going R&D and are candidate for short term integration in the codes.
