... of the devised setup is verified by finite element simulation and by reproducing in-plane curves obtained via an anti-buckling fixture. A shot peening process involving prevailing through-thickness deformation is modeled and numerical results indicate that employing only in-plane properties of magnesium sheets...

... using the X-ray diffraction technique. Numerical finite element (FE) models have attempted to model the shot peening process with some success. Since peening is a highly randomized process, the computational complexity of the problem increases significantly. Meguid et al. [ 9 , 10 ] modeled a detailed...
