Quantification 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...
متن کاملStress Variations Effect on the Accuracy of Slitting Method for Measuring Residual Stresses
To maintain the structural integrity of the engineering components, having an exact knowledge of residual stresses is important. Among all mechanical strain relief techniques to measure residual stresses, slitting is one of the youngest. This technique relies on the introduction of a narrow slot of increasing depth in a part containing residual stresses. Similar to other measurement techniques,...
متن کاملMeasurement of Residual Stresses by the Hole-Drilling* Strain Gage Method
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 کاملThermoelectric Nondestructive Evaluation of Residual Stress in Shot-Peened Metals
This paper presents a noncontacting thermoelectric method that can be used to characterize the prevailing residual stress in shot-peened specimens. This novel method is based on magnetic detection of local thermoelectric currents in the compressed near-surface layer of metals when a temperature gradient is established throughout the specimen. Besides the primary residual stress effect, the ther...
