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 simplifications that lead to approximat...
متن کاملResidual Stresses Measurement of a Quenched Cylinder using Slitting Method
Residual Stress measurement has gained interests among researchers for many years due to its great influence on the structural integrity. Slitting method is one of the destructive techniques that relies on the introduction of an increasing cut to a part containing residual stresses. Similar to all other mechanical strain relief techniques, slitting also suffers from its shortcomings during the ...
متن کاملQuantification of Residual Stresses in the Weld by the Hole-drilling Method
Many failures of supporting structures or machines are not caused only by stresses that are invoked by loading, but they often result due to residual stresses. Time needed for reparation of equipment and production losses are important factors, but much more serious are possible injuries or death of people. Residual stresses occur also in the structures without loadings. They arise mostly due t...

For technical support, contact [email protected] www.vishaymg.com 19 Revision 15-Aug-07 I. Residual Stresses and Their Measurement Residual (locked-in) stresses in a structural material or component are those stresses that exist in the object without (and usually prior to) the application of any service or other external loads. Manufacturing processes are the most common causes of r...
متن کاملeffects of free edge interlaminar shear stress on the residual stresses of polymer composites using hole drilling method
in the traditional hole drilling method the in-plane stresses are studied in detail and the interlaminar stresses are not taken seriously. the interlaminar stresses on the free edge of composite materials are important and can cause matrix cracking and delamination. inserting holes in composite laminates causes free edges and it can induce interlaminar shear and normal stresses. in this researc...
