Principle: How does this method work?
Applications: Some examples of measuring residual stresses
- To
see the method validated, check out the weld plate, bent beam, and friction stir weld
- See the validations page for a full list of published validation experiments.
Publications: Download detailed publications.
Veqter and Stress-Space in the UK provide measurement services with the contour method.
Hill Engineering has been licensed and performing contour method measurements in the USA since 2006.

"Residual
stresses in metals operate under a cloak of mystery, as they have neither
been seen in the laboratory nor detected by means of the microscope. In
spite of their phantom-like nature, they frequently exert metallurgical
effects that cannot be ignored."
- Kent R. VanHorn, Director
of Research, ALCOA, 1953, Journal of Metals, Vol. 197, pp 405-422.
