Plasticity Effect on Residual Stresses Measurement Using Contour Method
Residual stresses have become an important player in the field of the structural integrity for many years. Having an exact knowledge of residual stress distributions can be essential in designing the engineering components as unexpected failures are inevitable where such stresses are ignored. There are many residual stresses measurement techniques including destructive and non-destructive ones...
متن کاملResidual Stresses Measurement in Hollow Samples Using Contour Method
Residual stresses are created usually undesirably during manufacturing processes, including casting, welding, metal forming, etc. Residual stresses alone or in combination with other factors can cause the destruction and fracture of components or significant decline in their service life. Therefore, it is crucial to measure the residual stresses. Contour method is a destructive testing method c...
متن کاملEvaluation of Errors Associated with Cutting-Induced Plasticity in Residual Stress Measurements Using the Contour Method
Cutting-induced plasticity can lead to elevated uncertainties in residual stress measurements made by the contour method. In this study plasticity-induced stress errors are numerically evaluated for a benchmark edge-welded beam to understand the underlying mechanism. Welding and cutting are sequentially simulated by finite element models which have been validated by previous experimental result...
متن کاملResidual Stress Mapping in Welds using the Contour Method
The contour method, a newly-invented sectioning technique for residual stress measurement, has the potential to measure the cross-sectional residual stress profile of a weld in a simple and time-efficient manner. In this paper we demonstrate the capability of the contour method to measure cross-sectional residual stress profiles, which are compared with neutron diffraction measurements and show...
متن کاملResidual Stresses Measurement of a Quenched Cylinder using Slitting Method
Residual Stress measurement has gained interests among researchers for many years due to its great influence on the structural integrity. Slitting method is one of the destructive techniques that relies on the introduction of an increasing cut to a part containing residual stresses. Similar to all other mechanical strain relief techniques, slitting also suffers from its shortcomings during the ...
