Abstract

This paper presents some developments performed by EDF and FRAMATOME with the objective to define criteria for the consideration or not of Welding Residual Stresses within the Fracture Mechanics Assessment of nuclear components.

The paper is organised in two parts. In the first part, a literature survey is proposed, showing that major part of available results is at low temperature in the Brittle to Ductile transition where the effect of Welding Residual Stresses is known to be significant. This temperature domain is not relevant for nuclear applications; however, all those results are providing very important recommendations regarding the preparation of new testing.

In the second part, a numerical study is proposed for showing the relevance of the local approach for evaluating the impact of Residual Stresses on brittle fracture, and to initiate some criteria for defining the domain where they have a significant effect.

期刊介绍： Pressure vessel engineering technology is of importance in many branches of industry. This journal publishes the latest research results and related information on all its associated aspects, with particular emphasis on the structural integrity assessment, maintenance and life extension of pressurised process engineering plants. The anticipated coverage of the International Journal of Pressure Vessels and Piping ranges from simple mass-produced pressure vessels to large custom-built vessels and tanks. Pressure vessels technology is a developing field, and contributions on the following topics will therefore be welcome: • Pressure vessel engineering • Structural integrity assessment • Design methods • Codes and standards • Fabrication and welding • Materials properties requirements • Inspection and quality management • Maintenance and life extension • Ageing and environmental effects • Life management Of particular importance are papers covering aspects of significant practical application which could lead to major improvements in economy, reliability and useful life. While most accepted papers represent the results of original applied research, critical reviews of topical interest by world-leading experts will also appear from time to time. International Journal of Pressure Vessels and Piping is indispensable reading for engineering professionals involved in the energy, petrochemicals, process plant, transport, aerospace and related industries; for manufacturers of pressure vessels and ancillary equipment; and for academics pursuing research in these areas.
