متن کاملDual-axis Hole-drilling Espi Residual Stress Measurements
A dual-axis ESPI hole-drilling residual stress measurement method is described. It has the advantage of evaluating all the in-plane normal stress components with similar response to measurement errors, significantly lower than with single-axis measurements. Experimental tests were done on a stressed specimen, and the results supported theoretical expectations.
متن کاملRemarks on Residual Stress Measurement by Hole-Drilling and Electronic Speckle Pattern Interferometry
Hole drilling is the most widespread method for measuring residual stress. It is based on the principle that drilling a hole in the material causes a local stress relaxation; the initial residual stress can be calculated by measuring strain in correspondence with each drill depth. Recently optical techniques were introduced to measure strain; in this case, the accuracy of the final results depe...
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...
