Measure multiple stress components using one cut, multiple techniques, and superposition
To measure multiple stress components with multiple cuts see:
Pagliaro, P., Prime, M. B., Swenson, H., and Zuccarello, B., "Measuring Multiple ResidualStress Components Using the Contour Method and Multiple Cuts," Experimental Mechanics, 50(2), pp. 187194, 2010. (LAUR0901120)
Basic Contour Method:
The Contour
Method is Based on an Elastic Superposition Principle:
Start with your part. These
are the residual stresses that you would like to measure

Experimentally
cut the part in two. The part will deform
from the release of the stresses
Then experimentally
measure the contour, or shape, of the
newly created surface 


Now analytically
force the cut surface back flat. This
gives the original residual stresses normal to the cut plane!
It really is simple, but
gives you a full 2D map of the original residual stresses over the
crosssection of the part!
