Residual stresses play an important role in the behavior of structures
subjected to static and dynamic loads. The main aim of this study is to estimate experimentally the residual stresses in 70/30 brass material tested in bending and torsion using the plasticity theory. The influence of shot peening process on the tensile residual stresses is discussed. It is shown that the shot peening strongly influences the residual stresses, i.e. shot peening will reduce the tensile residual
stresses by 13.6% of the yield strength in bending tests. While will reduce the tensile residual stresses by 22% of shear yield stress in torsion tests.
