| Abstract: | The hole drilling technique is a well known experimental method for residual stress
investigation. This technique is usually used in combination with electrical strain gages but
there is no reason to enforce this choice and other approach are possible. In particular some
optical measurement techniques (grating interferometry, speckle interferometry, holographic
interferometry, shearography) can be advantageously used.
Since all these optical techniques give a full field information, it becomes important to properly
use their data to increase the robustness and reliability of the analysis. In this work, various
well known approaches to this problem will be investigated using a known displacement field
as a reference. In this way it will be possible to discover the best performing algorithm in terms
of robustness and reliability. |
