Residual elastic strain due to laser shock peening: modelling by eigenstrain distribution

Abstract:

High-energy synchrotron X-ray diffraction measurements of residual elastic strain were carried out in a thin slice parted off from a plate of titanium alloy that had been subjected to laser shock peening. The residual elastic strain varies with the distance from the laser shock peened surface, with high near-surface compressive strain changing to tensile strain in the middle of the sample, and then becoming compressive again on the opposite face. The measured residual elastic strain distribut...
