Combining Neutron Transmission and Diffraction for 2D Residual Stress Mapping of Cold-expanded Holes

Abstract: Neutron transmission has been able to produce 2D residual strain maps around cold expanded holes with high resolution, but limited to measurement of the axial strain direction. For engineering studies it is the hoop strain direction that is of primary interest. Here we propose to extend the information obtained from neutron transmission to other dierections, by complement it with a few extra diffraction measurements. The hypothesis is that hoop and radial strain can be extrapolated from the axial strain results, and therefore 2D stress maps can be reconstructed. Neutron diffraction measurement on ENGIN-X is proposed to prove this hypothesis. The experiment will be useful for the development of the neutron transmission technique for strain and stress measurements, especially considering IMAT will be able to perform combined neutron diffraction and transmission experiments.
