A numerical model of severe shot peening (SSP) to predict the generation of a nanostructured surface layer of material

Generation of a surface layer of material characterized by grains with dimensions up to 100 nm by means of severe plastic deformation is one of the most interesting methods to improve the mechanical behaviour of materials and structural elements. Among the ways to obtain a surface layer with this ch...
