Accurate prediction of residual stress in stainless steel welds

Autor: Lyndon Edwards, Mark Turski, R J Dennis, Michael Smith, P. J. Bouchard

Publikováno v: Computational Materials Science. 54:312-328

Measurements of stress–strain properties and residual stress in purpose-designed one and three-pass groove-weld specimens are used to optimise a mixed hardening constitutive model for simulating residual stresses in austenitic Type 316 stainless st

Influence of Phase Transformations on Residual Stresses in Welded Structures

Autor: Ondrej Muránsky, R J Dennis, Michael Smith, R S Kulka

Publikováno v: Volume 6B: Materials and Fabrication.

A key aspect of any numerical simulation to predict welding induced residual stresses is the development and application of an appropriate material model. Often significant effort is expended characterising the thermal, physical and hardening propert

Prediction of Welding Residual Stresses, Crack Initiation and Creep Crack Driving Forces C(t) Within a Continuous Finite Element Solution

Autor: R J Dennis, D. P. Bray, Michael Smith

Publikováno v: ASME 2010 Pressure Vessels and Piping Conference: Volume 6, Parts A and B.

The work reported in this paper investigates the manufacture, through-life operation and cracked behaviour of an attachment weld in a UK AGR boiler. A structural assessment of the attachment weld was performed to demonstrate its integrity. This asses

R6 Weld Modelling Guidelines: Application to Groove Weld Worked Example

Autor: R J Dennis, Neil A Leggatt, Michael Smith, P. J. Bouchard

Publikováno v: ASME 2010 Pressure Vessels and Piping Conference: Volume 6, Parts A and B.

Weld modelling guidelines have recently been developed as part of a new section of the R6 integrity assessment procedure, which is used in the UK nuclear power industry. The intention is to improve the consistency of weld modelling procedures, the ac

Modelling the Complex Manufacturing History of a Pipework Joint and Assessment of Its Through Life Creep-Fatigue Damage Using Finite Element Based Methods

Autor: R. A. W. Bradford, R. J. Dennis, D. P. Bray

Publikováno v: ASME 2010 Pressure Vessels and Piping Conference: Volume 6, Parts A and B.

The work reported in this paper investigates the complex manufacture and through-life operation of a pipework joint in a UK AGR boiler. Residual stresses resulting from the fabrication process can be a key driver for creep and creep-fatigue damage. T

Investigation of the Performance of the Contour Residual Stress Measurement Method When Applied to Welded Pipe Structures

Autor: E. A. Kutarski, R. J. Dennis, N. A. Leggatt

Publikováno v: Volume 6: Materials and Fabrication, Parts A and B.

The ‘Contour Method’ is a relatively new relaxation method for residual stress measurement and may be seen as an evolution of established methods such as hole drilling. The general procedure when applying the Contour Method is cutting, measuremen

Revised Weld Residual Stress and Creep Damage Assessments

Autor: A.R. Price, R J Dennis, M W Spindler, M C Smith

Publikováno v: Volume 6: Materials and Fabrication, Parts A and B.

Reheat cracking is a brittle inter-granular type of cracking that occurs in some types of stainless steel welds that have not been post-weld heat treated. It is caused by the accumulation of small creep strains that accompany the relaxation of the we
