Abstract:  
The advantages and disadvantages of existing methods of shot peening control are considered leading to a proposal that interactive control should be used in certain circumstances. A method of interactive control is proposed based on the use of linear variable displacement transducers to monitor the development of curvature during the shot peening process. This method uses disc-shaped test pieces rather that the traditional rectangular Almen strips. The need for different thicknesses of Almen strip, to cater for wide range of peening intensities, is eliminated by using different exposed areas of a given disc. The correlation between Almen intensity and disc curvature is considered in detail.
