A New Procedure for the Evaluation of Residual Stresses by the Hole Drilling Method Based on Newton-raphson Technique


The hole drilling method is one of the most used semi-destructive techniques for residual stress analysis of mechanical parts. In the presence of non-uniform residual stresses, the stress field can be determined from the measured relaxed strains using several methods, but the most used is the so called integral method. This method is characterized by some… (More)
