| Popis: | This paper presents a method for evaluating residual stresses. The approach is based on measuring the deformation due to the relief of stress produced by a drilled-hole or a ball indentation, and the deformation is rapidly measured by digital shearography. This method does not require mounting strain gages/transducers. Unlike holography, shearography does not require special vibration isolation. These features make the method practical for evaluation of residual stresses in a production/field environment. |
