Experimental Techniques (Methods): Residual Stress Determination

Experimental Techniques

Methods
As in all experimental methods, proper materials, application procedures, and instrumentation are essential if accurate results are to be obtained. The accuracy of the hole-drilling method is dependent chiefly upon the following technique-related factors:

strain gage selection and installation .
hole alignment and boring .
strain-indicating instrumentation .
understanding the mechanical properties of the test material.
