Apr 26, 2022 · Illustrated principle and actual applications of the contour method for cross-sectional mapping of residual stresses.

The contour method, first proposed in 2000 (57), is a newly invented relaxation method that enables a 2D residual stress map to be evaluated on a plane of interest.

Sep 23, 2013 · The contour method, which is based upon solid mechanics, determines residual stress through an experiment that involves carefully cutting a specimen into two pieces and …

The New Nuclear Manufacturing (NNUMAN) programme is currently making extensive use of the Contour Method to determine how residual stresses develop in thick-section ferritic steel plates.

The main advantage of the contour method is its ability to produce a 2-D map of residual stress acting normal to the cut surface. Other mechanical techniques, such as hole drilling, deep hole …

The contour method is a destructive technique to characterize the distribution of residual stresses in a part section in order to optimise production.

Aug 2, 2013 · The contour method determines residual stress by cutting a specimen into two pieces and measuring surface height maps, or contours, on the free surfaces created by the cut.

The contour method uses careful sectioning and precision inspection techniques to develop a two-dimensional map of residual stress on a plane through a part. The contour method was …

The principle behind measuring residual stresses by measuring the surface contour after a cut.

The contour technique is a destructive, mechanical strain release technique that is capable of measuring residual stresses in a single direction, in a two dimensional plane through a specimen.
