2D Residual Strain Mapping of Laser-shock Peened Aluminium using Bragg Edge Neutron Transmission

Abstract: Laser-shock peening (LSP) has emerged as surface treatment process to improve fatigue performance of aerospace structures. We wish to use Bragg edge neutron transmission to produce through-thickness average 2D strain maps of LSP samples. The aims of the experiment are: (1) Investigate the effect of different peening parameters, layering and patterning on the residual strains generated at the surface of the sample; (2) Demonstrate the capabilities of Bragg edge neutron transmission technique in direct comparison between the two only TOF imaging instruments: IMAT@ISIS and RADEN@J-Parc; (3) Develop the software tools for Bragg edge strain mapping. This experiment will showcase the capabilities of the new IMAT instrument for strain mapping of engineering samples.
