Data Management for the Evaluation of Residual Stresses by the Incremental Hole-Drilling Method

The semidestructive incremental hole drilling method commonly used to evaluate residual stresses is exceedingly sensitive to experimental errors, with sensitivity increasing as hole depth increases. To determine stress variations through the engine thickness, it is necessary to use accurate drilling methods, as well as suitable mathematical models and procedures to minimize the errors associated with residual stress measurement. This work examines he effects of measurement errors on the evaluation of residual stresses with the integral method
