Highlights
Wide range of engineering parts require specific treatment to improve their mechanical and/or corrosion resistance to enhance the fatigue, as well as the deformation resistance
This study presents an application of an inverse method to identify the stress–strain curve of materials subjected to high speed impacts like those occurring during the shot peening process
The inverse method was presented in Al Baida et al.,[13] and it was validated by blind tests on virtual materials and by experimental results on commercially pure copper
Summary
Wide range of engineering parts require specific treatment to improve their mechanical and/or corrosion resistance to enhance the fatigue (life), as well as the deformation resistance For such purposes, shot peening is one of the favorite candidates. Shot peening is one of the favorite candidates The principle of this process is to impact the metallic surface to be treated using small steel balls that create plastic strain, improve hardness, induce compressive residual stress, and increase the fatigue strength.[1]. In addition to the inverse method, an analytical approach has been used to obtain an estimation of the stress–strain curve The use of this second method aims at testing the validity of the inverse identification and increasing the confidence in the obtained results. This study presents applications of both the inverse method and the analytical approach to several industrial materials
