Abstract: 
Residual stresses are self equilibrium stresses and a portion of the strength of a specimen is used to tolerate these stresses. The effect of residual stresses depends On the magnitude and the direction of them in comparison with the external stresses could be useful or dangerous. Central hole drilling is the only method for measuring the residual stresses which are mentioned in ASTM standard.In this research, the central hole drilling process for thin components is simulated. This process has not been simulated by finite element method yet. Therefore, the model presented in this study can be used instead of the experimental methods. Two and three dimensional simulations are performed. After applying the load as the residual stresses, the elements in the region of the hole are removed. Then the strains in the locations of the strain gages are extracted and averaged. The comparison of the results obtained by this model and the ASTM standard method shows an error less than 3%.In three dimensional modeling, three plates with different thicknesses are modeled. The average strains for all elements in the region of the strain gages and the elements in the first layer of the model are calculated. The results of the simulation show a good agreement with the results of experimental standard method.
