In the present work a hole drilling procedure is used is to evaluate the uniform and non-uniform residual stresses resulted from aluminum plate subjected to heating source which in turn produce residual stresses of the isotropic aluminum plate either uniform or non-uniform stresses, however the aluminum plate is taken as case study. Then the data of strain is taken through hole drilling and investigated with procedure to examine it whether the distribution of strains are uniform or non-uniform, the final results was compared with standard curves. The final results of stresses are determined. The obtained result of residual stresses distribution is non-uniform. accordingly, method of the stresses distribution of any plate can be verified, also the number of residual stresses can be determined.
