RISResidual Stress Measurement by Successive Extension of a Slot: The Crack Compliance Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This article reviews the technical literature on the determination of a residual stress profile by successive extension of a slot and measurement of the resulting strains or displacements. This ...
Unified Model for Geomaterial Solid/Fluid States and the Transition in Between
Publisher: American Society of Civil Engineers
Abstract: During mudflows, geomaterials evolve in a very specific manner, because initially they behave as solids, and then they turn to flow as viscous fluids. This paper proposes an original approach to simulate, within a single ...
Surface Strains Due to Face Loading of a Slot in a Layered Half-Space
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A solution is presented that will allow the compliance method for residual stress measurement to be applied to layered materials. The solution is for surface strains due to arbitrary normal ...
Cross-Sectional Mapping of Residual Stresses by Measuring the Surface Contour After a Cut
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A powerful new method for residual stress measurement is presented. A part is cut in two, and the contour, or profile, of the resulting new surface is measured to determine the displacements ...
Uncertainty, Model Error, and Order Selection for Series-Expanded, Residual-Stress Inverse Solutions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Measuring the spatial variation of residual stresses often requires the solution of an elastic inverse problem such as a Volterra equation. Using a maximum likelihood estimate (least squares ...
Residual Stress Solution Extrapolation for the Slitting Method Using Equilibrium Constraints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Established methods for calculating residual stresses from the strains measured when using the slitting method give results for the stresses that exist within the depth range of the slit. ...
Three Dimensional Constraint Effects on the Slitting Method for Measuring Residual Stress
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The incremental slitting or crack compliance method determines a residual stress profile from strain measurements taken as a slit is incrementally extended into the material. To date, the inverse calculation of residual ...
Use of Inverse Solutions for Residual Stress Measurements
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: For most of the destructive methods used for measuring residual stresses, the relationship between the measured deformations and the residual stresses are in the form of an integral equation, ...
The Compliance Method for Measurement of Near Surface Residual Stresses—Analytical Background
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Introducing a thin cut from the surface of a part containing residual stresses produces a change in strain on the surface. When the strains are measured as a function of the depth of the ...
Measurement of Near Surface Residual Stresses Using Electric Discharge Wire Machining
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In previous work it has been shown that near surface residual stresses may be deduced from surface strains produced by making a cut of progressively increasing depth. The process of electric ...
