چكيده لاتين :
Experimental determination of residual stresses in thin sheets has been implemented by hole drilling
method. The incremental hole drilling technique is suggested as an acceptable technique for
determination of residual stress variation in thickness. In the present research, basic formulations of
converting experimentally measured strains into residual stress profiles have been studied. The number
of increments in drilling process affects the results. Two different set of tests have been used for
investigating this effect. A unidirectional tension test and a four point bending test are simulated by
FEM and the four point bending test (with same condition) is done experimentally. The drilling test has
been applied in 10, 20 and 40 increments. Comparison of the experimental and numerical results with
analytical result shows that by increasing the increment numbers, higher precision can be obtained and
stress profile results will be improved.
