Abstract:
This review has been carried out as an activity in project CPM4.5, on the Methods of Measuring Residual Stress in Components, which is part of the CPM programme on Characterisation and Performance of Materials, funded by the Engineering Industries Directorate of the UK Department of Trade and Industry. It is the deliverable for Task 1.The purpose of this review is to provide an overview of some of the recent advances in the area of residual stress measurement and act as a summary document to aid technique selection. The intention is not to duplicate what has already been published, because a number of comprehensive reviews of residual stress measurement methods are already available, but to provide advice and guidance on some of the issues associated with the measurement of residual stress.The results of a UK industrial survey of current interests and expertise in residual stress measurement are presented, together with guidelines on technique selection and some advice on quantifying the measurement uncertainty and accuracy. The physical limitations of the various techniques currently used are also summarised.
