Abstract:  
ABSTRACT A wide variety of experimental techniques have evolved which greatly enhance our knowledge and understanding of the shot peening process. Four technique categories are discussed relating to peening intensity, surface coverage simulation, shot properties and peened surface properties respectively. Peening intensity techniques include interactive intensity measurement and computer-fitted saturation curve procedures. Mathematical models have been developed for the prediction of surface coverage, the incidence of multiple impacting and indent diameters. Image analysis techniques have evolved for the quantification of shot properties such as size and shape variation. Surface property techniques include those for measurement and prediction of residual stress distributions, indentation size prediction and surface heating analysis. Examples are presented for each of the technique categories to illustrate the advantages and limitation of procedures that have been adopted.
