Abstract:  
The paper gives general steps for dynamic nonlinearity to shot peening mechanics. three dimensional constitutive material law expressed in stress invariants is used along with the nonlinear analysis based on the concept of initial stress. Residual stresses can be calculated using information in Gauss integration points. the corresponding shakedown modes can be interpreted as those which as state of equilibrium is no longer possible. The final results obtained the shakedown diagrams plotte in three dimensions.
