It brings together the expertise and experience of the project partners in a single document, and is being used to promote the transfer and uptake of the newly developed methodologies to a wider industry. Led by NPL and RomaTre and Oxford Universities, it is based largely on input and technical expertise of the project partners involved in Work Packages 2-5, and the results and findings from the various round robin exercises and studies carried out within the project. The GPG covers all aspects of the measurement process and residual stress analyses for the range of materials and sample geometries examined within the iSTRESS project. It is designed to be a practical guide, with advice, supporting information to illustrate the various process steps, and data analysis required to make reliable and repeatable high resolution residual stress measurements. Examples from the iSTRESS project are included throughout the document to illustrate aspects of the measurement process and highlight good practice. It forms an important document for pre-standardisation of the FIB-DIC technique and will continue to be promoted to the Standards community through CEN TC/352 and VAMAS TWA22 and is expected to form the basis of a future International Standard in this field.

The effect of surface damage and residual stresses on the fatigue life of nickel superalloys at high temperature

International Journal of Fatigue, Feb 1, 2019

Dents generated due to low velocity impacts of hard objects were simulated using a finite element (FE) model. The residual stress distribution underneath the dent root obtained numerically was compared with the measurements on experimentally simulated damaged specimens using ring-core milling at the micron scale through a combined Focused-Ion Beam and Digital Image Correlation technique (FIB-DIC). The numerical and experimental results for the residual stress show good agreement in terms of residual stress trends and magnitudes. The residual stress distribution obtained via the FE model was subsequently used in a fatigue short crack growth model for an estimation of the fatigue life of dented specimens. The fatigue life predictions were then compared with experimental fatigue results for the nickel superalloy at high temperatures. The comparison shows a significant improvement in the prediction of fatigue life of parts with superficial damage due to careful consideration of the residual stresses around the damage.
